[0002] As an important hydraulic structure, the construction of arch dams is a complex system engineering project, characterized by its large scale, long construction period, high quality control requirements, and complex resource allocation. Arch dam construction typically employs a skip-casting process, dividing the dam body into several sections, each section further divided into multiple blocks according to elevation, and then casting the dam in layers and blocks according to a specific sequence.

[0003] The existing arch dam casting simulation methods are mainly based on discrete system simulation theory, adopt traditional modeling and parameter calculation methods, focus on single progress simulation or local construction optimization, emphasize construction progress simulation and resource allocation, determine the casting sequence of dam blocks based on only a single factor, and do not consider other factors affecting the casting sequence, which makes the arch dam casting simulation results easy to be distorted, thus failing to guarantee the smooth implementation of the arch dam casting project. Summary of the Invention

[0007] In one alternative approach, the simulation method further includes: obtaining the overlap ratio between adjacent dam blocks to be poured in the exchanged pouring sequence; if the overlap ratio exceeds a preset ratio range, adjusting the sorting position of at least one of the adjacent dam blocks to be poured until the overlap ratio is within the preset ratio range.

[0008] In one alternative approach, the dam section to be poured is determined based on simulation parameters; the simulation method further includes: during the simulated pouring of the arch dam, if there is no grouting area that meets the preset joint grouting conditions, the simulation parameters are updated, and the simulated pouring of the arch dam is repeated based on the updated simulation parameters until the preset simulation termination conditions are met.

[0009] In one optional embodiment, the simulation method further includes: generating a dam block pouring simulation schedule and a joint grouting simulation schedule based on the updated simulation parameters; performing a temperature stress safety check based on the dam block pouring simulation schedule and the joint grouting simulation schedule to obtain a check result; if the check result exceeds a preset safety threshold, adjusting the updated simulation parameters and re-performing the arch dam simulation pouring based on the adjusted simulation parameters until the check result meets the preset safety threshold.

[0010] In one optional embodiment, the simulation method further includes: when the verification result meets the preset safety threshold and the arch dam simulation pouring is completed, obtaining the simulation analysis result feature parameters generated by the arch dam simulation pouring; if the simulation analysis result feature parameters do not meet the preset control target, then based on the difference between the simulation analysis result feature parameters and the control target, identifying the target simulation parameters that affect the progress target, and adjusting the target simulation parameters.

[0011] In one optional approach, adjusting the target simulation parameters includes: determining the adjustment direction and adjustment step size based on the adjustment strategy corresponding to the casting stage to which the target simulation parameters belong; adjusting the increase or decrease trend of the target simulation parameters according to the adjustment direction; and adjusting the increase or decrease magnitude of the target simulation parameters according to the adjustment step size.

[0012] In an optional embodiment, the simulation method further includes: if the verification result does not exceed the preset safety threshold, generating a construction resource configuration based on the dam block pouring simulation schedule and the joint grouting simulation schedule; and outputting the dam block pouring simulation schedule, the joint grouting simulation schedule, and the construction resource configuration.

[0013] In one optional approach, the dam blocks to be poured are weighted and sorted according to the pouring engineering parameters and the arch dam structural parameters to obtain the initial pouring sequence, including: weighting and summing the pouring engineering parameters and arch dam structural parameters corresponding to each dam block to be poured to obtain the priority score of each dam block to be poured; and determining the initial pouring sequence according to the priority score of each dam block to be poured and the preset parallel pouring requirements.

[0014] In one alternative approach, the cable crane information includes the spatial location, working status, and safe operating radius of each cable crane; configuring corresponding cable crane resources for the dam block to be poured based on the adjusted pouring sequence and cable crane information includes: selecting candidate cable cranes and operating parameters from the cable cranes in idle working status according to the spatial coordinates of the dam block to be poured; the range formed by the safe operating radius of the candidate cable cranes covers the spatial coordinates of the dam block to be poured.

[0027] The existing arch dam casting simulation methods are mainly based on discrete system simulation theory, adopt traditional modeling and parameter calculation methods, focus on single progress simulation or local construction optimization, emphasize construction progress simulation and resource allocation, determine the casting sequence of dam blocks based on only a single factor, and do not consider other factors affecting the casting sequence, which makes the arch dam casting simulation results easy to be distorted, thus failing to guarantee the smooth implementation of the arch dam casting project.

[0028] To address this issue, one aspect of this application provides a simulation method for arch dam casting to resolve the technical problem of distorted simulation results that fail to guarantee the smooth implementation of arch dam casting projects. Please refer to the following for details. Figure 1 , Figure 1 This is a schematic flowchart illustrating a simulation method for arch dam casting according to an exemplary embodiment of this application. The simulation method includes at least steps S110 to S140, which are described in detail below: S110 Obtain the dam section to be poured that meets the preset pouring conditions, and determine the dam block to be poured that meets the pouring requirements from the dam section to be poured.

[0029] The preset pouring conditions are a set of hard constraints set based on the construction appearance data collected in real time by the Internet of Things for engineering, including but not limited to the status of the site cleaning completion, the formwork installation in place, the rebar binding acceptance qualified, the temperature control measures ready, and the joint grouting preconditions being met.

[0030] The dam section to be poured is a dam section that meets the preset pouring conditions. It includes at least one dam block. The dam section to be poured is a dam body unit with independent structural boundaries and construction logic, divided according to the BIM (Building Information Modeling) model. Among them, the dam block is the smallest geometric unit within the dam section.

[0031] The pouring requirements include, but are not limited to, the requirements for concrete placement in the dam block and the current operation requirements. Dam blocks that meet the pouring requirements are those on which concrete placement can be carried out.

[0032] For example, a total of 8.03 million cubic meters of concrete were poured for the Baihetan Dam. 3 The dam, with 2300 sections and a complex structure, underwent a long construction period and was constructed using a group of seven double-layer horizontal moving cable cranes. In the Baihetan Dam simulation scenario, real-time construction data from an IoT platform was received, identifying section A on the right bank (Section III) where surface cleaning, formwork installation, and rebar acceptance had been completed. Further analysis of the BIM model of this section revealed three dam blocks—A-1, A-3, and A-5—that were ready for pouring. These blocks were then included in the set of dam blocks to be poured for subsequent sorting and resource allocation.

[0033] S120 assigns weights to the dam blocks to be poured based on the pouring engineering parameters and the arch dam structural parameters to obtain the initial pouring sequence.

[0034] Pouring parameters are dynamic process parameters that reflect the effectiveness of construction organization, including concrete transportation distance, pouring interval, cable crane accessibility, and the rate of mechanical placement on the pouring surface.

[0035] Arch dam structural parameters are structural parameters that characterize the geometric and mechanical properties of the dam body. These include the total dam elevation difference, the elevation difference between adjacent dam blocks (i.e., the pouring elevation difference between adjacent dam blocks to be poured), cantilever height, dam block thickness, spatial distance between the dam block and the arch crown beam, and stress gradient trend in the area where the dam block is located.

[0036] The initial pouring sequence represents the initial pouring order of each dam block to be poured. For example, if there are three dam blocks to be poured, namely A, B and C, the initial pouring sequence is obtained by weighting and sorting them based on their respective pouring engineering parameters and arch dam structural parameters, so that dam block B is poured first, then dam block C is poured, and finally dam block A is poured.

[0037] The weighted ranking is not a simple summation, but rather a linear weighted summation of the pouring engineering parameters and arch dam structural parameters after mapping them to normalized scores and then using preset weight coefficients to generate a comprehensive priority score for each dam block to be poured. The higher the score, the more priority the dam block to be poured should be arranged for pouring at the current simulation moment, so as to balance structural safety, construction efficiency and resource balance.

[0038] For example, based on the pouring engineering parameters and arch dam structural parameters corresponding to each dam block to be poured, the engineering dimension score and structural dimension score are calculated respectively, and then weighted and summed according to preset weights to obtain the priority score of each dam block; for example, the elevation difference parameter, cantilever height difference parameter and transportation distance parameter are processed by multi-objective normalization and then the priority score is synthesized, so as to sort the pouring order according to the priority score and obtain the initial pouring order of each dam block to be poured.

[0039] Another example involves weighted summation of the pouring engineering parameters and arch dam structural parameters corresponding to each dam block to be poured, yielding a priority score for each block. Based on the priority scores of each block and the pre-set parallel pouring requirements, the initial pouring sequence is determined. The pre-set parallel pouring requirements refer to the maximum number of dam blocks allowed to be poured simultaneously within the same time period, as defined in the construction organization plan. For example, by assigning weights to quantitative indicators such as the overall dam elevation difference, adjacent elevation differences, cantilever height, pouring intervals, and concrete transport distance for each block, the weighted indicators of the pourable blocks are superimposed to obtain the priority scores for each block. The initial pouring sequence is then obtained based on the maximum simultaneous pouring requirements (i.e., the pre-set parallel pouring requirements). For instance, all dam blocks are sorted from highest to lowest priority score, and the process is divided into several rounds with the pre-set parallel pouring number as the step size. Within each round, the dam blocks are considered as objects that can be poured in parallel, and the order of these rounds constitutes the initial pouring sequence.

[0040] S130 If there are consecutive preset numbers of dam blocks to be poured in the initial pouring sequence that belong to the same construction section, the initial pouring sequence will be adjusted to obtain the adjusted pouring sequence.

[0041] The number of consecutive presets is a threshold set based on construction organization experience, such as 3 or 5. This application does not limit its specific value.

[0042] A construction section refers to an independent construction unit based on an engineering contract or the division of construction management responsibilities. In the construction of large arch dam projects, the entire dam project is usually divided into several sections, which are then contracted out to different construction units. If a series of dam blocks to be poured belong to the same construction section, technical problems such as resource monopoly, precision imbalance, and management conflicts may arise.

[0043] The purpose of the adjustment is to break the concentrated sequencing of construction sections caused by similar structural or engineering parameters, and to avoid the risk of resource strain, personnel fatigue, or quality fluctuations caused by a section continuously undertaking high-intensity pouring tasks in a short period of time. This will prevent problems such as resource monopoly, management conflict, and precision imbalance. The adjustment does not change the overall priority framework, but rather, while maintaining the global sequencing trend, it interleaves and replaces local consecutive sequences of the same construction section, introducing cross-section dam blocks to participate in the sequencing reconstruction, thereby achieving a balance of construction load in the temporal and spatial dimensions.

[0044] For example, a target dam block is determined from a continuously preset number of dam blocks to be poured, specifying the final pouring order; alternative dam blocks with a pouring order prior to the target dam block are selected from the dam blocks to be poured in other construction sections; and the pouring orders of the target dam block and the alternative dam blocks are exchanged. The dam blocks to be poured in other construction sections are those belonging to different construction sections than the target dam block within the entire set of dam blocks to be poured, and their pouring order is prior to the target dam block.

[0045] For example, based on the section identifier and sequence number of each dam block to be poured in the initial pouring sequence, all dam blocks are scanned from front to back. A set of dam blocks whose section differs from the target dam block and whose sequence number is lower than the target dam block's sequence number is selected. The block with the largest sequence number is chosen as a replaceable dam block, allowing for precise positioning of replaceable dam blocks with both temporal precedence and section differences. Here, by identifying the final target dam block from consecutive dam blocks of the same section, selecting replaceable dam blocks from preceding dam blocks of different sections, and exchanging their pouring sequences, the distribution structure of construction sections is adjusted while maintaining the overall priority ranking stability. This avoids resource scheduling bottlenecks caused by continuous construction of a single section and ensures the temporal rationality of high-priority dam blocks, thereby improving the adaptability of the arch dam simulation pouring scheme to the real multi-section collaborative construction environment.

[0046] In some embodiments, a detailed method for adjusting the pouring sequence is provided, as detailed below: The overlap ratio between adjacent dam blocks to be poured in the exchanged pouring sequence is obtained; if the overlap ratio exceeds a preset ratio range, the order of at least one of the adjacent dam blocks to be poured is adjusted until the overlap ratio falls within the preset ratio range. The overlap ratio is, in the time dimension, the ratio of the overlapping time between the pouring operations of two adjacent dam blocks to the shorter of the two pouring periods. The overlap ratio is used to quantify the degree of coordination between adjacent dam blocks in terms of construction rhythm, and can serve as a criterion for determining whether adjacent dam blocks have a technologically feasible connection relationship. The preset ratio range serves as the basis for determining whether the overlap ratio meets the technological constraints. Its upper limit is used to prevent excessive overlap of the pouring times of adjacent dam blocks from causing resource conflicts, and its lower limit is used to avoid the risk of cold joints caused by excessively long intervals; this application does not limit its specific range value.

[0047] For example, based on the planned start time and duration of each of the adjacent dam blocks to be poured, the intersection length of their time windows is calculated, and then divided by the shorter pouring period to obtain the overlap ratio. If the overlap ratio between the current dam block to be poured and the next dam block to be poured is less than 0.15 (the lower limit of the preset ratio range) or greater than 0.45 (the upper limit of the preset ratio range), it is determined to be insufficient overlap. The next dam block to be poured is then shifted one position to the right in the sequence, so that the current dam block to be poured and the next dam block to be poured form a new adjacent pair, and the overlap ratio is recalculated. This process is repeated until the overlap ratio of all adjacent dam block pairs falls within the range of [0.15, 0.45] (the preset ratio range).

[0048] S140 configures the corresponding cable machine resources for the dam blocks to be poured based on the adjusted pouring sequence and cable machine information, so as to carry out the arch dam simulation pouring.

[0049] The cable crane information includes parameters such as the spatial coordinates of each cable crane, its working status (idle / operating / faulty), safe operating radius, maximum lifting weight, lifting speed, and lifting equipment type.

[0050] Cable crane resources include, but are not limited to, cable cranes used for pouring operations, as well as the operating parameters of the cable cranes, such as lifting weight and lifting speed.

[0051] For example, the cable crane information includes the spatial location, operating status, and safe operating radius of each cable crane. Based on the spatial coordinates of the dam block to be poured, candidate cable cranes and their operating parameters are selected from the cable cranes in idle operating status; the range formed by the safe operating radii of the candidate cable cranes covers the spatial coordinates of the dam block to be poured.

[0052] The idle working state represents the state in which the cable crane is not currently performing any work. A candidate cable crane is one whose spatial location is reachable from the spatial coordinates of the dam block to be poured, provided it meets the idle working state requirement. Operating parameters are capability parameters affecting operational feasibility, such as the cable crane's rated lifting capacity, maximum hoisting height, horizontal operating speed, hook luffing angle range, and real-time wind speed adaptability level. The safe operating radius is the radius within which the cable crane operates safely; the area formed by the safe operating radius can be understood as the three-dimensional space created by the cable crane's safe operation.

[0053] For example, candidate cable cranes can be screened by checking whether the Euclidean distance between the cable crane's spatial location and the spatial coordinates of the dam block to be poured is less than or equal to the cable crane's safe operating radius. If it is less than or equal to the safe operating radius, it indicates that the three-dimensional space in which the cable crane can safely operate covers the spatial coordinates of the dam block to be poured, and the cable crane is selected as a candidate cable crane for pouring the dam block.

[0054] For example, candidate cable cranes can be screened by considering whether the spherical working space defined by the safe operating radius of the cable crane includes the geometrical inclusion relationship of the spatial coordinates of the dam block to be poured; further, candidate cable cranes can be screened by considering whether the spatial vector modulus formed by the spatial location of the cable crane, the spatial coordinates of the dam block to be poured, and the topographic elevation difference between the two falls within the allowable range of the safe operating radius.

[0055] Figure 1 The illustrated embodiment determines the dam sections to be poured based on preset pouring conditions and selects the dam blocks to be poured according to the pouring requirements. By integrating pouring engineering parameters and arch dam structural parameters for weighted sorting, multi-objective collaborative optimization guided by structural safety and construction efficiency is achieved. Furthermore, the sequence of dam blocks in consecutive sections of the same contract is adjusted, improving the concentration of construction resources and making the adjusted pouring sequence more reasonable. Based on the adjusted pouring sequence and cable machine information, corresponding cable machine resources are configured for the dam blocks to be poured to conduct simulated arch dam pouring, improving the realism of the simulation results and providing data reference for real arch dam pouring projects to ensure the smooth implementation of arch dam pouring projects.

[0056] In another exemplary embodiment of this application, the method for judging the compliance of joint grouting is described in detail. Please refer to [link / reference] for details. Figure 2 , Figure 2 This is a flowchart illustrating an exemplary embodiment of the joint grouting compliance determination method. This joint grouting compliance determination method includes at least S210; wherein, the dam section to be poured is a dam section determined based on simulation parameters, detailed below: S210 If there is no grouting zone that meets the preset joint grouting conditions during the arch dam simulation casting process, the simulation parameters are updated, and the arch dam simulation casting is carried out again based on the updated simulation parameters until the preset simulation termination conditions are met.

[0057] Preset joint grouting conditions are one or more sets of constraints for concrete joint grouting of arch dams. They are used to characterize whether the grouting area has entered a state where joint grouting operations can be carried out, and are a key criterion for determining whether the simulation process needs to trigger parameter updates.

[0058] An irrigation district is a closed area enclosed by horizontal or vertical construction joints formed between adjacent dam blocks in an arch dam structure.

[0059] Simulation parameters are a set of parameters used to construct the dam section casting model, including but not limited to parameters affecting the dam block casting strength, intermittent pouring interval, cable crane scheduling rhythm, and pre-casting efficiency. Updating simulation parameters can be understood as updating the value of at least one simulation parameter, including but not limited to increasing / decreasing the concrete casting strength setting, extending / shortening the lower limit of the intermittent pouring interval, changing the cable crane group shift schedule, and modifying the resource allocation ratio for the two construction sections.

[0060] The preset simulation termination condition is at least one of the following: all dam blocks to be poured are completed, the simulation running time reaches the upper limit, or the cumulative number of iterations reaches a preset threshold. For example, if all dam blocks to be poured are completed, the simulation parameters will stop being updated, and the arch dam simulation pouring will stop being performed again based on the updated simulation parameters.

[0061] For example, during the simulated pouring process of the Baihetan Dam, the system tracks the completion time of the pouring of adjacent dam blocks in each irrigation area in real time. When the upstream dam block of an irrigation area has been poured for 28 days and the downstream dam block has been poured for 21 days, and the temperature difference between the two dam blocks is stable within ±3℃, it is determined that the irrigation area meets the preset joint grouting conditions. If no irrigation area that meets the conditions is identified within 3 consecutive simulation steps, the system automatically adjusts the intermittent period parameter of the dam surface from the original setting of 72 hours to 96 hours. Then, based on the updated parameters, the simulation state is re-initialized and a new round of pouring sequence optimization and cable crane resource configuration is started until all 2,300 dam sections are poured.

[0062] Figure 2 The embodiment shown uses irrigation area status monitoring as the key in the simulation process, and combines dynamic updates of simulation parameters with re-simulation execution to form a closed-loop control link. Without relying on manual intervention, it can autonomously generate a progress plan that conforms to the actual grouting process, effectively solving the technical problem that the simulation deviates from the actual construction due to the lack of grouting conditions, and improving the realism of the multi-process simulation process of high arch dams.

[0063] In another exemplary embodiment of this application, the impact of temperature stress safety verification on the simulated casting of the arch dam is considered; please refer to [link / reference needed]. Figure 3 , Figure 3 This is a schematic flowchart illustrating a temperature stress safety verification method according to an exemplary embodiment of this application. The temperature stress safety verification method includes at least steps S310 to S330, which are described in detail below: S310 generates a dam block pouring simulation schedule and a joint grouting simulation schedule based on the updated simulation parameters.

[0064] The dam block pouring simulation schedule is a time-segmented pouring sequence formed by taking the dam block to be poured as the spatial unit, the time axis as the dimension, and the cable crane resource allocation and pouring duration as constraints.

[0065] The joint grouting simulation schedule is a grouting operation sequence generated with the grouting area as the basic unit and the logical relationship of the grouting process (such as horizontal joints first and then longitudinal joints, and elevation from low to high) as the constraint conditions.

[0066] For example, based on the updated simulation parameters such as the concrete placement temperature setpoint, interval duration, and pouring layer thickness, combined with the cable crane operation efficiency and surface heat dissipation model, the start and end times of pouring each dam block are deduced, thereby generating a dam block pouring simulation schedule. Simultaneously, based on the updated simulation parameters such as the irrigation area temperature control parameters and grouting process constraints, combined with historical grouting efficiency data and irrigation area heat conduction response delay, the grouting operation sequence of each irrigation area is deduced, thereby generating a joint grouting simulation schedule.

[0067] S320 performs temperature stress safety verification based on the dam block pouring simulation schedule and the joint grouting simulation schedule, and obtains the verification results.

[0068] Temperature stress safety verification refers to the analytical process of evaluating, through simulation calculation, whether the internal stress of a concrete dam caused by temperature changes during construction exceeds the allowable bearing capacity of the concrete. It can be understood as checking whether the dam blocks will crack due to temperature changes.

[0069] The verification result can be a value that characterizes the safety level of temperature stress. The higher the value, the higher the safety level of temperature stress, and the less likely the dam block is to crack due to temperature changes.

[0070] For example, the start and end times of pouring, initial temperature, and adiabatic temperature rise curve of each dam block to be poured are determined according to the dam block pouring simulation schedule; the start and end times of grouting, the hydration heat release function of grouting material, and the contact stress increment caused by grouting pressure are determined according to the joint grouting simulation schedule; the determined parameters are input into the BIM model for simulation, and the dam body temperature and stress response are iteratively calculated at daily steps to determine the verification results of temperature stress safety check.

[0071] Another example is the construction simulation of the "diversion bottom hole construction period - before the flood discharge deep hole construction": The Baihetan diversion bottom hole uses a six-hole configuration. During this period, the elevation difference between the diversion bottom hole dam section and other dam sections gradually increases, resulting in an overall "M" shape for the dam body, which easily leads to a large cantilever height. If the allowable cantilever height of the dam body is limited, this period will severely affect the concrete pouring progress, thus affecting the formation of the joint grouting area, which in turn creates a new cantilever height difference affecting the pouring degree, creating a vicious cycle. Therefore, the key issue in controlling the pouring shape during this stage is cantilever height control.

[0072] The construction simulation in this phase simulated the dam pouring progress and appearance under different scenarios, including maximum allowable cantilever height and joint grouting technical requirements. Combined with the results of a special study on temperature control and stress, a height difference control scheme that ensured dam temperature control and stress safety while minimizing its impact on progress was comprehensively selected. Based on the measures proposed in the construction simulation, resources were concentrated to accelerate the construction progress of the diversion bottom hole; the pouring sequence was rationally arranged, and the pouring speed of higher dam sections was slowed down. Simultaneously, temperature control measures were implemented, and the joint grouting process was accelerated.

[0073] S330 If the verification result exceeds the preset safety threshold, the updated simulation parameters will be adjusted, and the arch dam simulation will be carried out again based on the adjusted simulation parameters until the verification result meets the preset safety threshold.

[0074] The verification result exceeding the preset safety threshold means that the maximum principal tensile stress value obtained from the temperature stress safety verification is greater than the allowable value in the specification, or the temperature gradient change rate of key parts exceeds the concrete crack resistance temperature control index.

[0075] Here, the temperature stress verification results are used as the driving signal to locate the key construction simulation parameters that cause the limits to be exceeded (such as high entry temperature, insufficient interval, and premature grouting). Only the simulation parameters of this type are adjusted, rather than resetting all simulation parameters. Based on the adjusted simulation parameters, the arch dam simulation pouring is carried out again to obtain new verification results until the verification results meet the preset safety threshold.

[0076] If the verification result does not exceed the preset safety threshold, then the construction resource configuration is generated based on the dam block pouring simulation schedule and the joint grouting simulation schedule; the dam block pouring simulation schedule, the joint grouting simulation schedule and the construction resource configuration are output.

[0077] Among them, construction resource allocation refers to the spatiotemporal distribution scheme of multi-dimensional resource elements, such as human resources (e.g., the number of steelworkers, formwork workers, and concrete workers), machinery and equipment (e.g., the number of shifts for cable cranes, concrete placing booms, and vibrating equipment), auxiliary materials (e.g., the amount of insulation blankets used and the density of cooling water pipe layout), and management resources (e.g., the scheduling of warehouse coordination personnel and the frequency of quality inspections), which need to be deployed to ensure the smooth implementation of the above two types of schedule plans. The above two types of schedule plans and construction resource allocation can be pushed to all participating parties, and the simulation plan and resource allocation can be realized through construction organization methods.

[0078] For example, in a simulation cycle of the Baihetan Dam in a certain year, the dam block pouring simulation schedule showed a peak of 16 consecutive dam block pouring sessions from day 120 to day 135, with a total concrete volume of 286,000 m³. Simultaneously, the joint grouting simulation schedule showed that from day 130 to day 145, 12 grouting zones covering the area entered the grouting window. Days 130 to 135 were identified as a peak period for both manpower and cable crane resources. The following construction resource allocation was generated: 120 steelworkers / day, 90 formwork workers / day, and 60 vibrator workers / day; three double-layer horizontal moving cable cranes were dedicated to pouring in this section, with one reserved for backup; 15,000 m³ of insulation blankets were provided, and the density of cooling water pipes was increased to 8 m / m²; and a joint inspection mechanism for the dam surface was established twice daily. This resource allocation scheme, together with the aforementioned two types of schedules, constitutes a complete set of construction instructions for on-site execution. The dam block pouring simulation schedule, joint grouting simulation schedule, and construction resource allocation are packaged together and uploaded to the cloud platform. After logging in, the general contractor can click on any dam block in the BIM lightweight view to instantly view its pouring time, associated irrigation area number, required number of steel reinforcement workers, on-duty cable crane number, and insulation blanket laying plan. The supervision unit can retrieve the resource load heat map to verify whether the resource allocation during peak periods meets the corresponding requirements. The owner's project management department can synchronously connect the schedule to the provincial smart construction management platform through the API (Application Program Interface) to achieve cross-level progress penetration supervision.

[0079] Figure 3 The embodiment shown uses the updated simulation parameters as the original parameters for generating the dual-schedule plan. Then, based on the dam block pouring simulation schedule and the joint grouting simulation schedule, a temperature stress safety check is performed. The temperature stress check results are used to implement closed-loop feedback adjustment of the simulation parameters. Finally, under the premise of ensuring the overall balanced and continuous rise of the arch dam, the temperature stress state of each construction stage is always within a controllable range.

[0080] In another exemplary embodiment of this application, the process of adjusting the target simulation parameters that affect the schedule objective is described; please refer to [link / reference needed]. Figure 4 , Figure 4 This is a flowchart illustrating an exemplary embodiment of the present application regarding the adjustment of target simulation parameters. The adjustment method includes at least steps S410 to S420, which are detailed below: S410 obtains the characteristic parameters of the simulation analysis results generated by the arch dam simulation casting when the verification results meet the preset safety threshold and the arch dam simulation casting is completed.

[0081] The characteristic parameters of the simulation analysis results are quantitative indicators characterizing the execution effect of the construction schedule plan after completing a full simulated arch dam pouring process. These include, but are not limited to, at least one of the following: total construction period, maximum daily concrete pouring intensity, average downtime of dam blocks on the critical path, average daily idle rate of cable cranes, peak resource utilization rate, distribution of continuous working days on the pouring surface, and construction balance index of the two sections. These characteristic parameters serve as a direct basis for evaluating whether the simulation plan has achieved its preset control objectives. Their values ​​are derived from the continuous recording and statistical summarization of the start and end times of pouring for each dam block to be poured, resource occupancy status, process connection relationships, and structural response data during the simulation process.

[0082] For example, in the simulation scenario of Baihetan Dam, when it is determined that all 2,300 dam blocks to be poured have been simulated and poured in the adjusted pouring sequence, and the temperature stress check result does not exceed the preset safety threshold (maximum tensile stress of the dam body < 2.5 MPa), the system automatically extracts the following parameters from the simulation log database: total simulation period is 1,082 days, maximum daily pouring volume is 21,000 m³, average comprehensive utilization rate of cable crane group is 78.3%, absolute difference in the number of pouring sections between the two sections is 47 sections, and average interval time between sections on the critical path is 42.6 hours. This set of parameters constitutes the characteristic parameters of the simulation analysis result of the current round, which is used to compare with the preset control target (total period ≤ 1,095 days, maximum daily pouring volume ≤ 22,000 m³, difference in balance between the two sections ≤ 30 sections).

[0083] S420 If the characteristic parameters of the simulation analysis results do not meet the preset control target, then based on the difference between the characteristic parameters of the simulation analysis results and the control target, the target simulation parameters that affect the schedule target are identified and adjusted.

[0084] The preset control target is a preset indicator used to measure the rationality of the construction schedule plan, including but not limited to at least one of the following: upper limit of total construction period, peak threshold of resource use, minimum inter-slab interval time, maximum allowable cantilever height, lower limit of construction balance between two sections, and coverage rate of joint grouting window period.

[0085] The target simulation parameters are those simulation parameters that are determined to have a significant impact on the progress target after difference identification, including but not limited to any one of the following: pouring interval time, cable crane operation efficiency, formwork turnover cycle, initial concrete setting time, grouting window period, or preparation time for the grouting surface.

[0086] For example, during the simulated pouring process at Baihetan, the total construction period in the simulation analysis results was 1098 days, which is greater than the total construction period of 1095 days in the control target. At the same time, the average comprehensive utilization rate of the cable crane group was 78.3%, which is lower than the ideal range (85%-92%). In other words, the characteristic parameters of the simulation analysis results do not meet the preset control target. It is determined that there is room for improvement in the cable crane transportation efficiency. Therefore, the cable crane transportation cycle and mechanical operation efficiency coefficient are identified as target simulation parameters that affect the progress target. The target simulation parameters can be adjusted by adjusting the cable crane transportation cycle and mechanical operation efficiency coefficient, and then written into the initialization configuration table of the next round of simulation to improve the simulation analysis results of the next round.

[0087] Figure 4 The illustrated embodiment identifies target simulation parameters that affect the schedule objective and implements targeted adjustments to them. This achieves a reverse mapping from simulation analysis results to input parameters. Without changing the underlying simulation model structure, it automatically locates key control parameters based on actual deviations, enabling timely adjustments to target simulation parameters and thus optimizing simulation analysis results.

[0088] This section provides an example of how to adjust the target simulation parameters: Based on the adjustment strategy corresponding to the pouring stage to which the target simulation parameters belong, the adjustment direction and adjustment step size are determined; the increase or decrease trend of the target simulation parameters is adjusted according to the adjustment direction, and the increase or decrease magnitude of the target simulation parameters is adjusted according to the adjustment step size. Different pouring stages have their own corresponding adjustment strategies; these strategies are a set of preset guidelines for parameter optimization behavior at different pouring stages, including the sensitive direction preferences, acceptable adjustment ranges, and convergence stability constraints for various types of target simulation parameters at each pouring stage.

[0089] The adjustment direction refers to the numerical change trend that the target simulation parameter should follow during iteration, which can be either an increase or a decrease. The adjustment step size refers to the quantization range by which the target simulation parameter is allowed to change during iteration, which can be a fixed value, a scaling factor, or a piecewise threshold.

[0090] For example, a preset adjustment strategy table is matched according to the type of the pouring stage, and the recommended adjustment direction and initial step size of the corresponding target simulation parameter are obtained by looking up the table; the confidence of the preset adjustment direction is dynamically corrected according to the stress monitoring data and temperature control feedback curve slope of the current pouring stage, and the adjustment step size is updated accordingly with weight; furthermore, the adjustment response effect of the target simulation parameter in the previous N iterations (such as the rate of change of characteristic parameters of the simulation results and the order of convergence) is combined with the sliding window statistical method to adaptively adjust the current step size.

[0091] For example, the grouting window period is identified as the target simulation parameter, belonging to the capping section, with the adjustment direction being extension and the adjustment step size being an extension of 1.2 days; its current value is read as 3.5 days, and an addition operation is performed to obtain an updated value of 4.7 days, which is then synchronized to the input interface of the joint grouting simulation submodule; subsequently, the constraint verification service is called to confirm that the extended window period still meets the requirement that the minimum interval time between adjacent grouting areas is ≥2.0 days, the verification is passed, and the target simulation parameter update takes effect.

[0092] By strongly correlating the adjustment behavior of the target simulation parameters with the pouring stage to which they belong, determining the adjustment direction and step size with the help of a preset adjustment strategy, and completing the parameter update through deterministic numerical calculation, the stage adaptability, directional controllability, and amplitude stability of the simulation parameter optimization process are achieved.

[0093] The following is an introduction to the complex construction scenario of the Baihetan Dam, involving 8.03 million m³ of concrete and 2,300 storage compartments: A balanced dam casting shape is beneficial for both casting quality and safety control, as well as for the continuous and balanced rise of the dam casting. The key to balance control is the comprehensive coordination and optimization of control parameters that reflect the balance of the dam casting appearance, such as the elevation difference between adjacent dam sections, the maximum elevation difference of the entire dam, and the maximum cantilever height.

[0094] Due to the influence of complex structures such as cavities, the pouring speed of different sections of the high arch dam varies greatly, and the pouring morphology control at different stages of the pouring process has different characteristics: (1) Initial stage of dam pouring In the initial stage of dam construction, dam body pouring and consolidation grouting are carried out simultaneously, and the dam's shape is easily affected by the consolidation grouting process. Typically, the ascent rate of the grouting section is much lower than that of the normal pouring. If consolidation grouting is performed on the first poured section, adjacent later poured sections may catch up and be suppressed by the earlier poured section, or even exceed the earlier poured section, requiring reverse jointing. If consolidation grouting is performed on the later poured sections, a significant elevation difference may easily form between them and the adjacent first poured sections. The adjacent first poured sections may have to reduce their ascent rate due to this large elevation difference. Furthermore, in the initial stage of dam construction, there are few sections being poured initially. If the pouring is uneven, it is easily restricted by the elevation difference between adjacent sections, leading to idle cable cranes and slow pouring progress.

[0095] Considering the characteristics of the initial stage of pouring, the construction simulation analysis focuses on the optimization of the consolidation grouting scheme and the analysis of the maximum adjacent height difference parameter: ①Optimal consolidation grouting scheme. Based on different parameters such as whether there is a cover weight, drilling and grouting efficiency, drilling volume, and grouting elevation, different consolidation grouting schemes are proposed. The impact of each scheme on the dam pouring progress and balance is analyzed through construction simulation program, and the optimal consolidation grouting scheme and pouring scheme are selected.

[0096] ② Analysis of the maximum adjacent elevation difference limit parameter. Typically, the elevation difference between adjacent dam sections is controlled to not exceed 12m. However, the pouring morphology is complex in the early stages of dam construction. Strictly adhering to the 12m limit may lead to resource waste or the formation of old concrete in higher sections due to prolonged waiting for adjacent lower sections to rise, affecting construction quality. Therefore, in the early stages of dam pouring, appropriately relaxing the adjacent elevation difference, combined with relevant temperature control and stress studies, is beneficial for accelerating the pouring progress and ensuring construction quality. Through construction simulation, the dam pouring progress and balance under different maximum adjacent elevation difference parameters are analyzed. Several schemes with significant impact on progress are selected, and combined with a special study on temperature control and stress, a suitable control scheme is finally chosen.

[0097] (2) Before the construction of the diversion bottom hole From the initial stage of dam construction to the commencement of the diversion bottom outlet, the number of dam sections being poured gradually increases, the foundation treatment of the riverbed dam sections is basically completed, and the pouring speed of each dam section is generally balanced. Through adjustments during this period, the initial unevenness in pouring gradually becomes more uniform. However, due to the influence of the foundation treatment of the bank slope dam sections, the bank slope dam sections are low, and the middle dam sections are high, forming an overall "convex" shape. The main problem in controlling the pouring shape at this stage is the issue of reverse joints in the bank slope dam sections, i.e., the originally lower dam section surpasses the adjacent higher dam section. The elevation of the reverse joint is generally at the boundary elevation of the joint grouting area, and the reverse joint process will generally affect the surpassed dam section for 15 to 25 days. If the reverse joint scheme is unreasonable, the impact may be even greater.

[0098] By utilizing construction simulation analysis and considering the actual site conditions, sensitivity analysis was conducted on factors such as the dam section's pouring time, inverted joint location, elevation constraints, and joint grouting conditions to select the optimal inverted joint location. Based on the measures proposed in the construction simulation analysis, a reasonable inverted joint scheme was selected during dam construction to minimize its impact.

[0099] (3) Construction period of the diversion bottom hole - before the construction of the flood discharge deep hole The Baihetan diversion channel employs a six-channel bottom outlet system. During this period, the elevation difference between the bottom outlet section and other dam sections gradually increases, resulting in an overall "M" shape for the dam body, which easily leads to significant cantilever heights. If the allowable cantilever height of the dam body is limited, this period will severely impact the concrete pouring progress, thereby affecting the formation of the joint grouting zone, creating new cantilever height differences that further affect the pouring progress, resulting in a vicious cycle. Therefore, the key issue in controlling the pouring pattern during this stage is cantilever height control.

[0100] The construction simulation in this phase simulates the dam pouring progress and appearance under different scenarios, including maximum allowable cantilever height and joint grouting technical requirements. Combined with temperature control stress research, a comprehensive elevation control scheme that ensures dam temperature control stress safety and minimizes its impact on progress is selected. Based on the measures proposed in the construction simulation, resources are concentrated to accelerate the construction progress of the diversion bottom hole; the pouring sequence is rationally arranged, and the pouring speed of higher dam sections is slowed down. Simultaneously, temperature control measures are implemented, and the joint grouting process is accelerated.

[0101] (4) Construction period of deep spillway - before construction of surface spillway The construction of the deep spillway involves concrete pouring at the orifice and installation of steel linings. During this period, the dam has an overall "U" shape, with a lower center and higher bank slopes. The middle riverbed section of the dam is prone to creating a significant elevation difference between the central section and the bank slope section. The transition sections from the riverbed section to the bank slope section (such as sections 13 and 23) are also prone to significant adjacent elevation differences, and the bank slope section is prone to creating a large cantilever height. Therefore, the dam body is poured during this period.

[0102] Taking into account the actual pouring appearance, surface structure, and resource allocation characteristics of this stage, sensitivity analysis of elevation control parameters and joint grouting schemes was conducted using construction simulation. Measures such as optimizing the steel lining installation scheme, reducing the interval of deep hole dam sections, and appropriately relaxing the cantilever height were proposed to optimize the elevation control scheme and ensure the balanced and continuous construction of the dam.

[0103] (5) Construction period of the spillway surface gate - Dam completion Before the construction of the surface spillway, the dam basically maintained a concave shape, with a lower center and higher bank slopes. During the surface spillway construction phase, the structure of the surface spillway section became more complex, and its ascent rate remained slow, while the bank slope section had a simpler structure, smaller area, and faster pouring speed. Therefore, the entire phase will maintain the concave shape. The key to shape control during this phase is coordinating the ascent rates of the riverbed dam section and the bank slope dam section, and appropriately adjusting the cantilever height restrictions.

[0104] Throughout the construction of the Baihetan Arch Dam, a personalized control principle was adopted, with individualized elevation and temperature control parameters applied to different parts of the dam and at different construction stages. The research on personalized control indicators organically combined dam temperature control and stress studies with dam construction progress simulation studies. Dynamic tracking studies were conducted as the dam pouring progressed, investigating the variation of the maximum principal stress extreme values ​​with increasing elevation control parameters in different dam sections at different grouting elevations, and the influence of elevation control parameters on the pouring progress of different pouring locations in different dam sections. Based on the combined results of temperature and stress studies and construction simulation studies at each stage, the optimal combination of elevation control parameters was selected.
