Description

Technical Field

[0001] The invention relates to the field of pile foundation construction resource assessment, in particular to a resource balanced optimization assessment method for construction feasibility of an offshore driven pile foundation. Background Art

[0002] Offshore driven pile foundation usually refers to a pile foundation construction technology that uses pile driving to sink precast piles into the seabed or riverbed to form a stable foundation in an offshore environment. This technology is widely used in marine engineering, port construction, offshore wind power and other fields to ensure that the structure has sufficient stability and bearing capacity under complex hydrogeological conditions. Offshore driven pile foundation mainly relies on the impact energy or static pressure of the pile hammer to drive the precast piles into the soil, so that the soil around the piles is compacted to form a stable bearing layer. Precast piles are usually made of reinforced concrete or prestressed concrete, with high strength and durability.

[0003] There are many factors that need to be considered during the construction of offshore driven pile foundations, such as the selection of pile-driving vessels and pile hammers, the selection of wind, wave and current window periods, construction period and cost control, and the order of piling. There is currently no mature experience to refer to for how to comprehensively consider the above factors to form a resource-balanced feasibility assessment of pile foundation construction. Therefore, in order to better guide the feasibility of offshore pile foundations in the early stages, a method and system for resource-balanced optimization assessment of the feasibility of offshore driven pile foundation construction is needed.

[0004] This method can effectively solve the problem of resource-balanced optimization assessment of the feasibility of offshore driven pile foundation construction. Compared with traditional assessment methods, this method comprehensively considers natural factors such as wind, waves and currents, construction equipment such as ships, pile foundation construction sequence selection and time control, and cost changes caused by such changes. The factors are relatively comprehensive, and the optimal or approximate optimal solution for the feasibility of offshore driven pile foundation construction is obtained through resource-balanced optimization. Summary of the invention

[0005] The present invention overcomes the shortcomings of the prior art and provides a resource-balanced optimization evaluation method for construction feasibility of an offshore driven pile foundation.

[0017] The pile foundation construction simulation system can simulate the flow state of seawater and wind in the target construction area, and can also simulate the driving process of the target pile foundation.

[0018] Further, in a preferred embodiment of the present invention, the feasibility test of the pile driving sequence of the target pile foundation is performed in the pile foundation construction simulation system, and based on the feasibility test result of the pile driving sequence, the target pile driving sequence of the target pile foundation is obtained, specifically:

According to different type of pile foundation distances, a distance sorting table is constructed in ascending order and calibrated as a pile foundation distance sorting table.

[0023] Taking the simulated starting pile foundation as the center, determine whether there is a simulated target pile foundation within the target distance threshold, and if so, mark the simulated target pile foundation within the target distance threshold as a type of simulated target pile foundation, and based on the pile foundation distance sorting table, select a type of simulated target pile foundation as the next intended simulated target pile foundation based on the principle of the smallest type of pile foundation distance;

[0024] If there is no simulated target pile foundation within the target distance threshold, the simulated target pile foundation is selected as the next simulated target pile foundation to be constructed based on the principle of the smallest distance of a type of pile foundation in the pile foundation distance sorting table;

[0025] A construction feasibility analysis is performed on the construction position of the simulated target pile foundation to be constructed, and a target piling sequence of the target pile foundation is generated based on the construction feasibility analysis results.

If so, simulate the construction of the corresponding simulated target pile foundation intended for construction to obtain a constructed simulated target pile foundation, and continue to retrieve and simulate the construction of the next simulated target pile foundation intended for construction based on the target distance threshold and the simulated starting pile foundation, until all the simulated target pile foundations intended for construction are constructed simulated target pile foundations;

[0030] Analyze the pile foundation construction exchange record table. If there is no construction sequence exchange between the intended simulated target pile foundation and the corresponding obstacle simulated target pile foundation, then exchange the construction sequence between the intended simulated target pile foundation and the corresponding obstacle simulated target pile foundation, and continue to simulate the construction of the intended simulated target pile foundation until all the intended simulated target pile foundations are constructed simulated target pile foundations.

[0031] If there has been an exchange of construction order between the intended simulated target pile foundation and the corresponding obstacle simulated target pile foundation, it is determined that there is a pile-eating between the intended simulated target pile foundation and the corresponding obstacle simulated target pile foundation, and the construction of the current intended simulated target pile foundation is stopped, and the next intended simulated target pile foundation is retrieved and simulated based on the target distance threshold and the simulated starting pile foundation, until all intended simulated target pile foundations are constructed simulated target pile foundations;

[0032] The simulated construction sequence of all simulated target pile foundations is obtained to obtain the target piling sequence of the target pile foundation.

[0033] Further, in a preferred embodiment of the present invention, the construction resource evaluation of the simulated target pile foundation is performed in the pile foundation construction simulation system, and after the construction resource evaluation, the construction resources are balanced and optimized to obtain a target piling plan for the target pile foundation, specifically:

[0034] In the pile foundation construction simulation system, based on the target piling sequence of the target pile foundation, simulate the construction of the simulated target pile foundation, and record the different processes in the simulated construction process in real time;

[0035] Among them, the different processes in the simulated construction process include the simulated target pile foundation loading process, the simulated target pile foundation transportation process, the simulated target pile foundation driving process and the simulated target pile foundation clamping process;

[0036] Preset the construction collection time period. During the construction simulation process of the pile foundation construction simulation system, when the simulated construction time passes through a construction collection time period, the process running in the construction collection time period will be calibrated as the real-time running process;

[0037] Obtain all construction collection time periods, and obtain the construction resource intensity value of the corresponding real-time operation process within all construction collection time periods, wherein the construction resource intensity value is the resource amount of all resources supporting the pile foundation construction simulation system to perform simulated construction;

[0038] Based on all the construction collection time periods and the corresponding construction resource intensity values, an initial construction resource intensity dynamic curve chart is constructed, and the peak values ​​of the construction resource intensity in different construction collection time periods are obtained on the initial construction resource intensity dynamic curve chart;

[0039] Obtain a big data network, retrieve the highest construction resource intensity value that will be reached when constructing a target pile foundation based on the big data network, and calibrate it as a peak value of the construction resource intensity;

[0040] A comprehensive analysis is conducted on the peak value of construction resource intensity and the peak value of construction resource intensity in different construction collection time periods, and based on the comprehensive analysis results, the construction resources are balanced and optimized to obtain the target piling plan for the target pile foundation.

[0041] Furthermore, in a preferred embodiment of the present invention, a comprehensive analysis is performed on the peak value of the construction resource intensity and the peak value of the construction resource intensity in different construction collection time periods, and the construction resources are balanced and optimized based on the comprehensive analysis results to obtain a target piling plan for the target pile foundation, specifically:

[0042] Obtain the construction collection time period corresponding to the peak value of the construction resource intensity that is greater than the peak value of the construction resource intensity, and mark it as the construction collection time period to be analyzed;

[0043] Calculate the construction resource sub-intensities of all real-time operation processes running in the construction collection time period to be analyzed, and arrange all real-time operation processes running in the construction collection time period to be analyzed in descending order according to the construction resource sub-intensities, so as to obtain a sorting table of real-time operation processes;

[0044] The sorting table of the first type of real-time operation process is analyzed. If there are real-time operation processes with the same construction resource sub-intensity among all the real-time operation processes running within the construction collection time period to be analyzed, the corresponding real-time operation processes are combined into real-time operation processes with the same construction resource sub-intensity;

[0045] Calculate the adjustable time differences of all real-time operation processes with the same sub-intensity of construction resources, and sort the real-time operation processes with the same sub-intensity of construction resources based on the principle of small to large adjustable time differences, and obtain the sorting result of the adjustable time differences, and update the sorting table of the first category of real-time operation processes based on the sorting result of the adjustable time differences to obtain the sorting table of the second category of real-time operation processes;

[0046] In the second category real-time operation process ranking table, the importance of all real-time operation processes is retrieved based on the big data network, and the real-time operation process with the lowest importance is marked as a non-critical process, and the non-critical process is set as the tail process of the second category real-time operation process ranking table to obtain a target real-time operation process ranking table;

[0047] The target real-time operation process sequencing table is output, and a target piling plan for the target pile foundation is constructed in combination with a target piling sequence of the target pile foundation.

[0048] The second aspect of the present invention further provides a construction feasibility resource balance optimization evaluation system for an offshore driven pile foundation, the construction feasibility resource balance optimization evaluation system comprising a memory and a processor, the memory storing a construction feasibility resource balance optimization evaluation method, and when the construction feasibility resource balance optimization evaluation method is executed by the processor, the following steps are implemented:

[0050] Conduct a feasibility test of the pile driving sequence of the target pile foundation in the pile foundation construction simulation system, and obtain a target pile driving sequence of the target pile foundation based on the feasibility test result of the pile driving sequence;

[0051] The construction resource evaluation of the simulated target pile foundation is carried out in the pile foundation construction simulation system, and after the construction resource evaluation, the construction resources are balanced and optimized to obtain the target piling plan of the target pile foundation.

The method can comprehensively plan the factors that need to be considered in the construction process of offshore driven pile foundations and evaluate the construction feasibility, so as to achieve the purpose of maximizing resource utilization and improving piling efficiency.

[0057] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0058] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0059] Figure 1 A flow chart of a resource-balanced optimization evaluation method for construction feasibility of an offshore driven pile foundation is shown, comprising the following steps:

[0060] Conduct simulation modeling of the construction system of the offshore driven pile foundation, and determine the relevant resource parameters of the construction system of the offshore driven pile foundation during the simulation modeling process;

[0061] Conduct a feasibility test of the pile driving sequence of the target pile foundation in the pile foundation construction simulation system, and obtain a target pile driving sequence of the target pile foundation based on the feasibility test result of the pile driving sequence;

[0062] The construction resource evaluation of the simulated target pile foundation is carried out in the pile foundation construction simulation system, and after the construction resource evaluation, the construction resources are balanced and optimized to obtain the target piling plan of the target pile foundation.

[0063] Furthermore, in a preferred embodiment of the present invention, the construction system of the offshore driven pile foundation is simulated and modeled, and the relevant resource parameters of the construction system of the offshore driven pile foundation are determined during the simulation modeling process, specifically:

[0064] The construction area is marked as a target construction area, and the driven pile foundation that needs to be driven into the target construction area is marked as a target pile foundation;

[0065] Introducing environmental monitoring equipment in the target construction area, wherein the environmental monitoring equipment includes equipment for monitoring the flow velocity of seawater in the target construction area and equipment for monitoring the wind speed;

[0066] The seawater flow velocity and wind speed in the target construction area are monitored in real time by the environmental monitoring equipment, and are calibrated as the real-time seawater flow velocity and the real-time wind speed in the target construction area;

[0067] All equipment controlling the driving of the target pile foundation in the target construction area are calibrated as ship machinery equipment, wherein the ship machinery equipment includes a pile driving ship, a barge, a tugboat, and a crane ship, and the working parameter range of all the ship machinery equipment is obtained;

[0068] Acquire three-dimensional simulation software, in which a simulation system for constructing a target pile foundation is constructed based on the working parameter range of all ship machinery equipment, the real-time seawater flow velocity in the target construction area, and the real-time wind speed in the target construction area, and is calibrated as a pile foundation construction simulation system;

[0069] The pile foundation construction simulation system can simulate the flow state of seawater and wind in the target construction area, and can also simulate the driving process of the target pile foundation.

[0070] It should be noted that the target construction area is the area that needs to be piled. There is a target pile foundation in the target construction area, and the target pile foundation needs to be driven into the corresponding position of the target construction area. Since the piling is driven offshore, it is necessary to obtain the real-time flow rate of seawater and the real-time wind speed in the target construction area, and at the same time obtain the working parameter range of all equipment for driving the target pile foundation. The purpose of obtaining the above data is to facilitate the construction of a pile foundation construction simulation system that fully simulates the target construction area in reality. The simulated construction of the target pile foundation in the pile foundation construction simulation system is the same as the construction of the target pile foundation in reality. Through the simulation system, it is also possible to observe in real time the problems that may exist in the simulated construction process and solve them.

[0071] Further, in a preferred embodiment of the present invention, the feasibility test of the pile driving sequence of the target pile foundation is performed in the pile foundation construction simulation system, and based on the feasibility test result of the pile driving sequence, the target pile driving sequence of the target pile foundation is obtained, specifically:

[0072] A log module is preset in the pile foundation construction simulation system, wherein the log module can record all operation steps in the pile foundation construction simulation system in real time;

[0073] Obtaining the position where the target pile foundation needs to be driven, marking it as the target driving position, and marking the target driving position as the target simulated driving position in the pile foundation construction simulation system;

[0074] The simulation model corresponding to the target pile foundation in the pile foundation construction simulation system is calibrated as a simulated target pile foundation, all the target pile foundations are matched with all the target simulated driving positions, and a simulated target pile foundation is selected and calibrated as a simulated starting pile foundation, and a distance threshold is preset and calibrated as a target distance threshold, wherein the simulated starting pile foundation is the first successfully constructed simulated target pile foundation;

[0075] The distances between different simulated target pile foundations and simulated starting pile foundations are calculated and calibrated as a type of pile foundation distances. According to different type of pile foundation distances, a distance sorting table is constructed in ascending order and calibrated as a pile foundation distance sorting table.

[0076] Taking the simulated starting pile foundation as the center, determine whether there is a simulated target pile foundation within the target distance threshold, and if so, mark the simulated target pile foundation within the target distance threshold as a type of simulated target pile foundation, and based on the pile foundation distance sorting table, select a type of simulated target pile foundation as the next intended simulated target pile foundation based on the principle of the smallest type of pile foundation distance;

[0077] If there is no simulated target pile foundation within the target distance threshold, the simulated target pile foundation is selected as the next simulated target pile foundation to be constructed in the pile foundation distance sorting table based on the principle of the smallest distance of a type of pile foundation.

[0078] It should be noted that the log module can record all the operating steps in the pile foundation construction simulation system. When all the operating steps are recorded, the target piling sequence of the target pile foundation can be produced. All target driving positions need to be driven into pile foundations. First, the starting pile foundation is determined. The starting pile foundation is the first pile foundation that has been successfully constructed. With the starting pile foundation as the center, if there is a simulated target pile foundation within the distance range of a type of pile foundation, then the pile foundation is the intended pile foundation, that is, the next pile foundation to be constructed. If not, the corresponding simulated target pile foundation with the smallest distance to a type of pile foundation is required as the intended pile foundation, so it is necessary to determine the pile foundation distance sorting table to facilitate the determination of the intended pile foundation. The above method can construct all simulated target pile foundations in a faster and more efficient manner.

[0079] Further, in a preferred embodiment of the present invention, the construction feasibility analysis is performed on the construction position of the simulated target pile foundation to be constructed, and the target piling sequence of the target pile foundation is generated based on the construction feasibility analysis result, specifically:

[0080] Determine whether there is a construction position for the simulated target pile foundation intended for construction. If so, simulate the construction of the corresponding simulated target pile foundation intended for construction to obtain a constructed simulated target pile foundation, and continue to retrieve and simulate the construction of the next simulated target pile foundation intended for construction based on the target distance threshold and the simulated starting pile foundation, until all the simulated target pile foundations intended for construction are constructed simulated target pile foundations;

[0081] If there is no construction position for the intended simulated target pile foundation, the constructed simulated target pile foundation with the shortest distance to the intended simulated target pile foundation shall be marked as the obstacle simulated target pile foundation;

[0082] Obtaining a pile foundation construction exchange record table, wherein the pile foundation construction exchange record table records whether there is an exchange of construction sequences between the intended simulated target pile foundation and the corresponding obstacle simulated target pile foundation;

[0083] Analyze the pile foundation construction exchange record table. If there is no construction sequence exchange between the intended simulated target pile foundation and the corresponding obstacle simulated target pile foundation, then exchange the construction sequence between the intended simulated target pile foundation and the corresponding obstacle simulated target pile foundation, and continue to simulate the construction of the intended simulated target pile foundation until all the intended simulated target pile foundations are constructed simulated target pile foundations.

[0084] If there has been an exchange of construction order between the intended simulated target pile foundation and the corresponding obstacle simulated target pile foundation, it is determined that there is a pile-eating between the intended simulated target pile foundation and the corresponding obstacle simulated target pile foundation, and the construction of the current intended simulated target pile foundation is stopped, and the next intended simulated target pile foundation is retrieved and simulated based on the target distance threshold and the simulated starting pile foundation, until all intended simulated target pile foundations are constructed simulated target pile foundations;

[0085] The simulated construction sequence of all simulated target pile foundations is obtained to obtain the target piling sequence of the target pile foundation.

[0086] It should be noted that each intended pile foundation has a corresponding construction position. If the construction position can be found, it is considered that the current intended pile can be constructed. The intended pile foundation is constructed, and the above steps are repeated until all pile foundations are constructed. If the construction position cannot be found, it proves that a constructed pile causes the intended pile to be unable to be constructed, that is, the constructed pile hinders the construction of the intended pile. The obstacle pile corresponding to the intended pile is the pile foundation closest to the intended pile, so the obstacle simulation target pile foundation can be determined according to the distance. The two piles can realize the retrieval of the construction position by exchanging the construction sequence, because the two piles may vacate the construction position after the construction sequence is exchanged. First, it is necessary to determine whether there is a construction sequence exchange record for the two piles. The pile foundation construction exchange record table can be used to determine whether there is a construction sequence exchange record for the two piles. If not, the construction sequence of the two piles is exchanged, and both piles are constructed until all pile foundations are completed. If there is a construction sequence exchange record, it proves that two piles cannot be constructed at the same time at this position. If two piles are constructed at the same time at this position, the piles will be eaten and construction cannot be carried out. At this time, the construction of the current intended simulated target pile foundation is stopped, and the next intended simulated target pile foundation is retrieved and simulated based on the target distance threshold and the simulated starting pile foundation, until all intended simulated target pile foundations are constructed simulated target pile foundations. When all pile foundations are completed, the order of all pile foundation construction is recorded to obtain the target piling order of the target pile foundation.

[0087] Figure 2 A flow chart of a method for evaluating construction resources and optimizing construction resources for simulating a target pile foundation in a pile foundation construction simulation system is shown, comprising the following steps:

[0088] S202: Determine different processes in the simulated construction process in the pile foundation construction simulation system;

[0089] S204: Calculate the peak value of construction resource intensity and the peak value of construction resource intensity in different construction collection time periods;

[0090] S206: Comprehensively analyze the peak value of construction resource intensity and the peak value of construction resource intensity in different construction collection time periods, and balance and optimize the construction resources based on the comprehensive analysis results to obtain a target piling plan for the target pile foundation.

[0091] Further, in a preferred embodiment of the present invention, the construction resource evaluation of the simulated target pile foundation is performed in the pile foundation construction simulation system, and after the construction resource evaluation, the construction resources are balanced and optimized to obtain a target piling plan for the target pile foundation, specifically:

[0092] Preset the construction collection time period. During the construction simulation process of the pile foundation construction simulation system, when the simulated construction time passes through a construction collection time period, the process running in the construction collection time period will be calibrated as the real-time running process;

[0093] Obtain all construction collection time periods, and obtain the construction resource intensity value of the corresponding real-time operation process within all construction collection time periods, wherein the construction resource intensity value is the resource amount of all resources supporting the pile foundation construction simulation system to perform simulated construction;

[0094] Based on all the construction collection time periods and the corresponding construction resource intensity values, an initial construction resource intensity dynamic curve chart is constructed, and the peak values ​​of the construction resource intensity in different construction collection time periods are obtained on the initial construction resource intensity dynamic curve chart;

[0095] The big data network is obtained, and the highest construction resource intensity value that will be reached when constructing the target pile foundation is retrieved based on the big data network, and is calibrated as the peak value of the construction resource intensity.

[0096] It should be noted that after obtaining the different processes in the simulated construction process, multiple construction collection time periods need to be preset. In the simulation construction process, when the simulation time advances a construction collection time period, it is necessary to check which processes are under construction in the construction collection time period that has just passed, that is, to determine what real-time operation processes exist in a construction collection time period. The process needs to consume resources when it is running, and the resources include but are not limited to the number of transport ships consumed, the number of pile drivers, and the amount of oil consumed by pile drivers. The construction resource intensity values ​​of the corresponding real-time operation processes in all construction collection time periods are obtained, and based on the initial construction resource intensity dynamic curve chart, the peak values ​​of the construction resource intensity in different construction collection time periods are obtained. The peak values ​​of the construction resource intensity in different construction collection time periods are the total amount of construction resources in different construction collection time periods. In this time period, the construction resource intensity that can be supported cannot exceed this number. The big data network is a database that records different data and schemes. Based on the big data network, the maximum construction resource intensity value required for construction of all real-time operation processes in the same time period is obtained, which is calibrated as the peak value of the construction resource intensity.

[0097] Furthermore, in a preferred embodiment of the present invention, a comprehensive analysis is performed on the peak value of the construction resource intensity and the peak value of the construction resource intensity in different construction collection time periods, and the construction resources are balanced and optimized based on the comprehensive analysis results to obtain a target piling plan for the target pile foundation, specifically:

[0098] Obtain the construction collection time period corresponding to the peak value of the construction resource intensity that is greater than the peak value of the construction resource intensity, and mark it as the construction collection time period to be analyzed;

[0099] Calculate the construction resource sub-intensities of all real-time operation processes running in the construction collection time period to be analyzed, and arrange all real-time operation processes running in the construction collection time period to be analyzed in descending order according to the construction resource sub-intensities, so as to obtain a sorting table of real-time operation processes;

[0100] The sorting table of the first type of real-time operation process is analyzed. If there are real-time operation processes with the same construction resource sub-intensity among all the real-time operation processes running within the construction collection time period to be analyzed, the corresponding real-time operation processes are combined into real-time operation processes with the same construction resource sub-intensity;

[0101] Calculate the adjustable time differences of all real-time operation processes with the same sub-intensity of construction resources, and sort the real-time operation processes with the same sub-intensity of construction resources based on the principle of small to large adjustable time differences, and obtain the sorting result of the adjustable time differences, and update the sorting table of the first category of real-time operation processes based on the sorting result of the adjustable time differences to obtain the sorting table of the second category of real-time operation processes;

[0102] In the second-category real-time operation process ranking table, the importance of all real-time operation processes is retrieved based on the big data network, and the real-time operation process with the lowest importance is marked as a non-critical process, and the non-critical process is set as the tail process of the second-category real-time operation process ranking table to obtain a target real-time operation process ranking table;

[0103] The target real-time operation process sequencing table is output, and a target piling plan for the target pile foundation is constructed in combination with a target piling sequence of the target pile foundation.

[0104] It should be noted that the peak value and peak value of construction resource intensity in the same construction collection time period are analyzed. If the peak value of construction resource intensity is greater than the peak value of construction resource intensity, it proves that it is necessary to reasonably allocate resources and balance planning for real-time operation processes to achieve reasonable utilization of resource intensity. In the construction collection time period to be analyzed, the priority postponement principle is applied. The priority postponement principle is divided into three stages. The first stage is to prioritize the postponement of real-time operation processes with low resource intensity. By calculating the resource intensity occupied by different real-time operation processes, that is, the construction resource sub-intensity, the real-time operation processes are sorted to obtain a sorting table of a class of real-time operation processes. The second stage is that if the construction resource sub-intensity is equal, the real-time operation process with a large adjustable time difference is prioritized. The adjustable time difference is a process that can freely adjust the running time, which can also be understood as a process that can freely allocate time and does not need to be completed in the first time. According to the adjustable time difference sorting result, the sorting table of a class of real-time operation processes is updated to obtain a sorting table of a class of real-time operation processes. The third stage is to postpone the non-critical process that can be postponed to the end of the time period after the adjustment of the first and second stages to the end of the time period, that is, to set the non-critical process as the tail process of the second category real-time operation process sorting table.
