Description

Technical Field

[0001] The embodiments of the present invention relate to the field of hydropower engineering, and in particular to a coupling simulation method and device based on a dam BIM model and a finite element model. Background Art

[0002] Large-scale hydropower projects are mostly located in areas with complex environments. The construction technology is difficult and the working area is limited. The overall construction efficiency is severely restricted. In addition, the quality requirements of hydropower projects are high and there are many participating units, which makes the construction process more and more complicated. Relying solely on traditional methods to formulate progress plans cannot fully demonstrate the deviations in the progress caused by environmental and construction factors, nor can it accurately estimate the quality and safety problems that will arise from construction according to the progress plan. The uncertainty of the construction process makes the control and coordination of the construction progress of the entire project face severe challenges. Summary of the invention

Through simulation, this embodiment can predict in advance whether the current construction plan meets the contract node duration of the target hydropower project, and when the current construction plan does not meet the contract node duration of the target hydropower project, by multiple adjustments to the simulation boundary parameters corresponding to the current construction plan, a schedule that meets both the contract node duration of the target hydropower project and the structural safety results is obtained, thereby ensuring the feasibility and safety of the schedule. This embodiment couples the feasibility and safety of the adjusted schedule through multiple adjustments of the simulation boundary parameters, thereby avoiding the delay in construction progress due to uncertainty in the construction process in related technologies, which leads to the failure to meet the contract node duration of the target hydropower project, and also avoids safety issues caused by arbitrary adjustments to the current schedule.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0073] Please refer to Figure 1 , Figure 1 FIG. 1 is a flow chart of a coupled simulation method based on a dam BIM model and a finite element model according to an embodiment of the present invention. Figure 1 As shown, the method may include steps S11 to S15:

[0074] Step S11: Determine the value of the simulation boundary parameter based on the acquired current construction environment data, construction plan information and design plan information of the target hydropower project; the current construction environment data at least includes: project terrain data, currently completed project parts, and on-site monitoring data.

[0075] In this embodiment, for the target hydropower project, the current construction environment data, construction plan information and design plan information of the target hydropower project can be obtained first. Among them, the target hydropower project is a hydropower project that needs to be evaluated for construction progress and structural safety. The current construction environment data at least includes: project terrain data, currently completed project parts, and on-site monitoring data, such as the currently completed part of the project and the topographic parameters of the project.

[0076] Among them, based on the current construction environment data, an engineering database and an initial building information model (Building Information Modeling, BIM) can be established to realize the visualization and integrated unified management of the current construction environment information. The initial building information model and engineering database can be directly obtained through the data interface engine to avoid data loss and omission caused by repeated input and output during the data acquisition process.

[0077] In this embodiment, the values ​​of the simulation boundary parameters can be determined based on the acquired current construction environment data, construction plan information and design plan information of the target hydropower project. In this embodiment, the values ​​corresponding to multiple simulation boundary parameters can be formulated.

[0078] Furthermore, in one embodiment, the values ​​of the simulation boundary parameters can be determined based on water conservancy construction specifications, on-site construction resources, design plan information, construction plan information, and contract node duration.

[0079] Step S12: constructing a building information model with an additional time dimension based on the values ​​of the simulation boundary parameters.

[0080] In this embodiment, a building information model of an additional time dimension (i.e., a dam BIM model) can be constructed based on the determined values ​​of the simulation boundary parameters, wherein the building information model of the additional time dimension is a building information model related to the engineering schedule of the additional time dimension.

[0081] For example, a building information model with an additional time dimension may be constructed based on the proposed values ​​of the simulation boundary parameters and the initial building information model.

[0082] Step S13: Based on the building information model, the schedule of each node of the target hydropower project is obtained.

[0083] In this embodiment, after the building information model with the additional time dimension is constructed, the construction period of each node schedule of the target hydropower project can be predicted based on the building information model with the additional time dimension.

[0084] Step S14: Based on the planned construction periods of each node and the contractual node construction periods of the target hydropower project, determine whether the construction period of the target hydropower project meets the requirements.

[0085] In this embodiment, after obtaining the schedule construction period of each node output by the building information model with an additional time dimension, the schedule construction period of each node can be compared with the contract node construction period corresponding to the target hydropower project to determine whether the contract construction period of the target hydropower project meets the requirements, that is, to determine whether the schedule of the target hydropower project meets the contract construction period.

[0086] Step S15: When the construction period does not meet the requirements, based on the current construction environment data, the construction plan information and the design plan information, the values ​​of the simulation boundary parameters are re-determined; based on the re-determined values ​​of the simulation boundary parameters, the step of constructing a building information model with an additional time dimension is re-executed until the step of determining whether the construction period of the target hydropower project meets the requirements, until it is determined that the construction period of the target hydropower project meets the requirements.

[0087] In this embodiment, when it is determined that the contract duration of the target hydropower project does not meet the requirements based on the planned construction period of each node and the contract node duration corresponding to the target hydropower project, that is, when it is determined that the progress plan of the target hydropower project does not meet the contract duration, the values ​​of each simulation boundary parameter can be re-determined based on the current construction environment data, construction plan information and design plan information obtained.

[0088] In this embodiment, the building information model with an additional time dimension can be reconstructed based on the re-determined values ​​of the simulation boundary parameters; then, based on the reconstructed building information model with an additional time dimension, a new node schedule corresponding to the target hydropower project can be obtained; finally, based on the new node schedule corresponding to the target hydropower project and the contract node schedule of the target hydropower project, it is re-determined whether the construction period of the target hydropower project meets the requirements, until it is determined that the construction period of the target hydropower project meets the requirements.

[0089] Step S16: When the construction period meets the requirements, a structural safety review is performed based on the structural stress of the target hydropower project in the time dimension to obtain a structural safety result of the target hydropower project.

[0090] In this embodiment, when it is determined that the contractual construction period of the target hydropower project meets the requirements based on the planned construction period of each node and the contractual node construction period corresponding to the target hydropower project, the structural safety of the target hydropower project can be reviewed according to the structural stress of the target hydropower project in the time dimension to obtain the structural safety result of the target hydropower project.

[0091] Step S17: When the structural safety result of the target hydropower project is that the schedule structure is unsafe, based on the current construction environment data, the construction plan information and the design plan information, the values ​​of the simulation boundary parameters are re-determined; based on the re-determined values ​​of the simulation boundary parameters, the step of constructing a building information model with an additional time dimension is re-executed until the step of determining whether the construction period of the target hydropower project meets the requirements, until it is determined that the structural safety result of the target hydropower project is that the schedule structure is safe.

[0092] In this embodiment, when the structural safety result of the target hydropower project is determined to be that the schedule structure of the target hydropower project is unsafe, the values ​​of each simulation boundary parameter can be re-determined based on the acquired current construction environment data, construction plan information and design plan information.

[0093] After obtaining the re-determined values ​​of each simulation boundary parameter, the building information model of the additional time dimension can be reconstructed based on the re-determined values ​​of the simulation boundary parameters; secondly, based on the reconstructed building information model of the additional time dimension, the new node schedule plan period corresponding to the target hydropower project is obtained; then, based on the new node schedule plan period corresponding to the target hydropower project and the contract node schedule of the target hydropower project, it is re-determined whether the construction period of the target hydropower project meets the requirements, until it is determined that the construction period of the target hydropower project meets the requirements; then, based on the new structural stress of the target hydropower project in the time dimension, a structural safety review is performed to obtain the structural safety result of the target hydropower project, until it is determined that the new structural safety result of the target hydropower project is the schedule structural safety of the target hydropower project, and it is determined that the construction progress of the target hydropower project is in line with expectations and the structural safety assessment result.

[0094] In the coupled simulation method based on the dam BIM model and the finite element model proposed in this embodiment, considering the uncertainty of the construction process, in order to control and coordinate the construction progress of the target hydropower project, this embodiment proposes a coupled simulation method based on the construction progress and structural safety, the simulation boundary parameters corresponding to the current construction plan are simulated to obtain the schedule construction period, and when the schedule construction period does not meet the contract node construction period of the target hydropower project, the simulation boundary parameters are adjusted to obtain a new construction plan and then simulated until the schedule construction period meets the contract node construction period of the target hydropower project, so that a feasible schedule is obtained; further, in order to ensure the safety of the feasible schedule, the simulation boundary parameters corresponding to the feasible schedule are simulated to obtain the structural safety result of the target hydropower project, and when the structural safety result of the target hydropower project is that the schedule structure is unsafe, the simulation boundary parameters are adjusted to obtain a new construction plan and then simulated until the new construction plan meets both the contract node construction period of the target hydropower project and the structural safety result is that the schedule structure is safe, and finally a feasible and safe schedule is obtained. Through simulation, this embodiment can predict in advance whether the current construction plan meets the contract node duration of the target hydropower project, and when the current construction plan does not meet the contract node duration of the target hydropower project, by multiple adjustments to the simulation boundary parameters corresponding to the current construction plan, a schedule that meets both the contract node duration of the target hydropower project and the structural safety results is obtained, thereby ensuring the feasibility and safety of the schedule. This embodiment couples the feasibility and safety of the adjusted schedule through multiple adjustments of the simulation boundary parameters, thereby avoiding the delay in construction progress due to uncertainty in the construction process in related technologies, which leads to the failure to meet the contract node duration of the target hydropower project, and also avoids safety issues caused by arbitrary adjustments to the current schedule.

[0095] In combination with the above embodiments, in one implementation, the present invention further provides a coupling simulation method based on a dam BIM model and a finite element model. In the method, the above step S16 may specifically include steps S21 to S23:

[0096] Step S21: When the construction period meets the requirements, the model information acquirer in the finite element analysis model is used to acquire the physical quantity information related to each unit, each node and each unit or each node of the target hydropower project in the building information model to generate engineering structure data.

[0097] In this embodiment, when it is determined that the contractual construction period of the target hydropower project meets the requirements based on the planned construction period of each node and the contractual node construction period corresponding to the target hydropower project, the building information model with an additional time dimension can be imported into the finite element analysis model through the data interface for calculation, and the structural safety of the target hydropower project can be reviewed to obtain the structural safety results of the current construction project of the target hydropower project.

[0098] Specifically, in this embodiment, for building information models in different file formats, a model information acquirer is defined in the finite element analysis model, and the model information acquirer in the finite element analysis model can be used to obtain each unit, each node and physical quantity information related to each unit or each node of the target hydropower project in the building information model of the additional time dimension to generate engineering structure data; wherein, the engineering structure data is a general data structure.

[0099] It can be understood that what can be obtained through the model information acquirer is the physical quantity information related to each unit of the target hydropower project that meets the construction period requirements in the building information model, or the physical quantity information related to each node, or the physical quantity information related to each node and each unit, thereby obtaining the general engineering structure data corresponding to the target hydropower project.

[0100] Step S22: using the finite element analysis model, based on the engineering structure data, calculate the structural stress of the target hydropower project in the time dimension.

[0101] In this embodiment, after obtaining the general engineering structure data corresponding to the target hydropower project, the structural stress of the target hydropower project in the time dimension of each unit and / or node can be calculated based on the acquired engineering structure data through a finite element analysis model (also called a finite element model).

[0102] Step S23: Performing a structural safety review based on the structural stress of the target hydropower project in the time dimension to obtain a structural safety result of the target hydropower project.

[0103] In this embodiment, after obtaining the structural stress of the target hydropower project in the time dimension, the structural safety of the target hydropower project can be reviewed according to the structural stress of the target hydropower project in the time dimension to obtain the structural safety result of the target hydropower project.

[0104] In this embodiment, construction information and current construction conditions are monitored in real time, a construction schedule that meets the construction period requirements is formulated through a building information model with an additional time dimension, the physical quantities of each unit node of the target hydropower project in the building information model are extracted and analyzed in combination with finite elements, and the structural stress of the target hydropower project under the time dimension of each unit node is verified by the extracted engineering structure data through the finite element analysis model. Through the coupling of the building information model with an additional time dimension and the finite element analysis model, the construction progress and structural safety of the hydropower project are mutually bounded, the feasibility and safety of the real-time schedule of the target hydropower project are fully verified, and scientific, refined and intelligent methods and means are provided for the full process, dynamic and visual control of the integrated progress of the hydropower project, and the construction progress and safety of the current hydropower project construction are displayed in real time.

[0105] In combination with the above embodiments, in one implementation, the present invention further provides a coupling simulation method based on a dam BIM model and a finite element model. In the method, the above step S16 may specifically include steps S31 to S32:

[0106] Step S31: When the structural stress satisfies the structural safety condition, determining the structural safety result of the target hydropower project as the schedule structural safety.

[0107] In this embodiment, a safety threshold of structural stress is set in advance. After the structural stress of the target hydropower project in the time dimension is obtained, the structural stress of the target hydropower project in the time dimension can be compared with the safety threshold of the structural stress. When it is determined that the structural stress of the target hydropower project in the time dimension is lower than the safety threshold of the structural stress, it is determined that the structural stress of the target hydropower project in the time dimension meets the structural safety condition. When the structural stress meets the structural safety condition, the structural safety result of the target hydropower project is determined to be the schedule plan structural safety of the target hydropower project.

[0108] Step S32: when the structural stress does not satisfy the structural safety condition, determining the structural safety result of the target hydropower project as a schedule-planned structural unsafety.

[0109] In this embodiment, when it is determined that the structural stress of the target hydropower project in the time dimension is higher than the safety threshold of the structural stress, it is determined that the structural stress of the target hydropower project in the time dimension does not meet the structural safety conditions. When the structural stress does not meet the structural safety conditions, the structural safety result of the target hydropower project is determined to be that the schedule plan structure of the target hydropower project is unsafe.

[0110] In combination with the above embodiments, in one implementation, the present invention further provides a coupling simulation method based on a dam BIM model and a finite element model. In the method, the above step S11 may specifically include steps S51 to S52, and the above step S15 or step S17 may specifically include S53:

[0111] Step S51: Based on the construction plan information, determine the parameter range of the simulation boundary parameter.

[0112] In this embodiment, the parameter range of each simulation boundary parameter can be determined based on the construction plan information of the target hydropower project. The parameter range is the value range of the parameter, and any value within the parameter range is acceptable.

[0113] Step S52: Based on the current construction environment data and the design scheme information, an initial value of the simulation boundary parameter is obtained within the parameter range of the simulation boundary parameter.

[0114] In this embodiment, after the parameter range of each simulation boundary parameter is determined, the initial value of each simulation boundary parameter can be obtained within the parameter range of each simulation boundary parameter based on the acquired current construction environment data and design scheme information.

[0115] Step S53: Based on the current construction environment data and the design scheme information, the value of the simulation boundary parameter is re-determined within the parameter range of the simulation boundary parameter to obtain a new value of the simulation boundary parameter.

[0116] In this embodiment, in the process of redetermining the values ​​of the simulation boundary parameters, the values ​​of the simulation boundary parameters are re-determined within the parameter range of the simulation boundary parameters determined in step S51 based on the current construction environment data and design scheme information of the target hydropower project to obtain new values ​​of the simulation boundary parameters.

[0118] And, in this embodiment, after the values ​​of the simulation boundary parameters are re-drafted, the initial value of at least one simulation boundary parameter among the simulation boundary parameters is different from the new value. That is, when the simulation boundary parameters are re-drafted, for the multiple simulation boundary parameters, the value of at least one simulation boundary parameter changes, that is, the initial value of at least one simulation boundary parameter is different from the new value.

In addition, in this embodiment, the building information model can be used to more vividly display the construction process of the target hydropower project, which can provide effective support and intuitive visual effects for real-time adjustment of progress.

[0124] In combination with the above embodiments, in one implementation, the present invention further provides a coupled simulation method based on a dam BIM model and a finite element model. In this method, in addition to the above steps, steps S71 and S72 may also be included:

[0125] Step S71: When the construction period does not meet the requirements, the first construction site with delayed progress in the target hydropower project is determined based on the comparison results of the planned construction period of each node and the contract node construction period of the target hydropower project, and an early warning message is output. The early warning message at least includes: the construction progress of the first construction site is delayed.

[0126] In this embodiment, when it is determined that the construction period does not meet the requirements, the first construction site of the target hydropower project that is lagging behind in progress can be determined based on the comparison results of the planned construction period of each node and the contract node construction period of the target hydropower project, and an early warning message is output. Among them, the first construction site is a construction site in the target hydropower project where the construction progress does not meet the construction period requirements and is in a lagging state; the early warning information is warning information of the construction progress, and the early warning information at least includes: the construction progress of the first construction site is lagging behind. This embodiment can push the early warning information and make relevant reminders: such as flashing the screen, issuing an early warning sound, etc.

[0127] Step S72: When the structural stress does not meet the structural safety condition, determine a second construction location in the target hydropower project where the structural stress exceeds the safety threshold, and output an alarm message, wherein the alarm message at least includes: the structural stress of the second construction location exceeds the standard.

[0128] In this embodiment, when it is determined that the structural stress does not meet the structural safety conditions, the second construction site where the structural stress in the target hydropower project exceeds the corresponding safety threshold can be determined, and an alarm message can be output. Among them, the second construction site is the construction site where the structural stress in the target hydropower project exceeds the corresponding safety threshold; the alarm message is the warning message of the structural stress, and the alarm message at least includes: the structural stress of the second construction site exceeds the standard. This embodiment can push the alarm message and make relevant reminders: such as flashing the screen, issuing an alarm sound, etc. Among them, the alarm sound and the early warning sound of this embodiment can be the same or different, and can be freely set.

The same construction period node requirements; if the contract construction period node requirements are not met, the simulation boundary parameters are redetermined until the contract construction period node requirements are met; if the contract construction period node requirements are met, the BIM model of the additional time dimension that meets the construction period requirements is obtained, and the finite element analysis model is used to conduct a structural safety review to determine whether the structural safety requirements are met; if the structure meets the safety requirements, the schedule planning and safety verification of the target hydropower project are completed, and construction continues according to the schedule; if the structure does not meet the safety requirements, the simulation boundary parameters are redetermined until the schedule planning and safety verification of the target hydropower project are finally completed.
