Description

Technical Field

[0001] The present invention relates to the technical field of construction management, and more specifically, to a subway construction project management system and method based on BIM. Background Art

[0002] With the acceleration of the urbanization process, the subway, as an important part of urban transportation, has an increasingly large construction scale, and the construction complexity has also increased accordingly. The traditional management method of subway construction projects often relies on manual experience and paper drawings, making it difficult to achieve comprehensive and accurate management of the construction process. At the same time, there are many uncertain factors in the subway construction process, such as complex geological conditions, high technical difficulties, and tight construction periods. These factors pose great challenges to the construction project management.

[0003] In recent years, Building Information Modeling (BIM) technology has been widely used in the field of construction management. By creating a three-dimensional model, BIM technology integrates all the information of an engineering project, providing intuitive and comprehensive visual support for project management. However, most of the existing BIM-based construction management systems focus on the construction of the model and static display, lacking dynamic management of the construction process and risk resistance analysis.

[0004] To overcome the deficiencies of the prior art, the present invention proposes a subway construction project management system and method based on BIM. The system realizes the construction and dynamic update of the subway construction model by setting up a subway construction building block module, an expected data setting module, an expected plan generation module, and a plan risk resistance analysis module. It can automatically generate multiple construction plans according to the expected data of various construction data periodically, and select the cycle construction plan with the best comprehensive risk resistance ability through risk resistance analysis for construction. This innovative management method and system not only improve the efficiency and accuracy of construction management, but also enhance the risk resistance ability of the construction process, providing a strong guarantee for the smooth progress of subway construction projects. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a subway construction project management system and method based on BIM.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A subway construction project management system based on BIM includes a subway construction building block module, an expected data setting module, an expected plan generation module, and a plan risk resistance analysis module;

[0008] The subway construction building block module is used to construct a subway construction BIM model and update the subway construction BIM model in real time;

[0009] The expected data setting module sets the expected data of various construction data for the subway construction project in the next project management cycle every time a project management cycle passes.

[0010] The expected plan generation module is used to input the expected data of various construction data into the subway construction BIM model, and the subway construction BIM model generates construction plans for p cycles.

[0011] The plan risk resistance analysis module is used to obtain the construction plan risk resistance value of each cycle's construction plan, mark the cycle construction plan with the largest construction plan risk resistance value as the management execution plan, and use the management execution plan to construct the subway construction project in the next project management cycle.

[0012] Further, the method for obtaining the construction plan risk resistance value of the cycle construction plan is as follows: Determine a cycle construction plan, determine all risk types existing in the subway construction project, and then obtain the risk resistance values of each risk type. Sum up and take the average of the risk resistance values of all risk types to obtain the average risk resistance value Shdg. Match all risk types in pairs to form a resistance combination group, obtain the resistance combination value of each resistance combination group, sum up and take the average of the resistance combination values of all resistance combination groups to obtain the average resistance combination value Wdsj, and use the formula to obtain the construction plan risk resistance value Fygv of this cycle construction plan, where n1 is the average risk resistance coefficient and n2 is the average resistance combination coefficient.

[0013] Further, the method for obtaining the resistance combination value of the resistance combination group is as follows: Sum up the risk resistance values of the two risk types in the resistance combination group to obtain the comprehensive resistance value Bnkw, calculate the difference between the risk resistance values of the two risk types in the resistance combination group and take the absolute value to obtain the resistance difference value Dprb, and use the formula to obtain the resistance combination value Haxe of this resistance combination group, where u1 is the resistance difference coefficient.

[0014] Further, the method for obtaining the risk resistance value of a risk type is as follows: Determine the risk parameters involved in a risk type, input the periodic construction plan and the risk parameters involved in this risk type into the subway construction BIM model. The subway construction BIM model conducts a simulated construction for one project management cycle. After the simulated construction is completed, obtain the construction inspection values of various construction data. Based on the comparison results of the construction inspection values with the high construction inspection value and the low construction inspection value, mark the construction data as inspection-satisfactory data, inspection-disappointing data, and inspection-normal data. Mark the total number of inspection-satisfactory data as Sati, mark the total number of inspection-disappointing data as Lhop, sum up and take the average of the construction inspection values of all inspection-normal data to obtain the inspection normal value Hbzp. Use the formula to obtain the risk resistance value Eskt of this risk type, where v1 is the quantity influence coefficient and v2 is the inspection normal coefficient.

[0015] Further, to obtain the construction inspection values of various construction data, specifically: Collect the construction cut-off data of various construction data, obtain the corresponding construction inspection models for various construction data, and input the construction cut-off data of various construction data into the corresponding construction inspection models respectively to obtain the construction inspection values of various construction data.

[0016] Further, based on the comparison results of the construction inspection values with the high construction inspection value and the low construction inspection value, mark the construction data as inspection-satisfactory data, inspection-disappointing data, and inspection-normal data, specifically: Set the high construction inspection value and the low construction inspection value. When the construction inspection value of the construction data is greater than or equal to the high construction inspection value, mark this construction data as inspection-satisfactory data. When the construction inspection value of the construction data is less than or equal to the low construction inspection value, mark this construction data as inspection-disappointing data. When the construction inspection value of the construction data is between the high construction inspection value and the low construction inspection value, mark this construction data as inspection-normal data.

[0017] Further, the BIM-based subway construction project management method includes the following steps:

[0018] Step 1: Construct a subway construction BIM model and update the subway construction BIM model in real time;

[0019] Step 2: Every time a project management cycle passes, set the expected data of various construction data for the subway construction project in the next project management cycle;

[0020] Step 3: Input the expected data of various construction data into the subway construction BIM model, and the subway construction BIM model generates p periodic construction plans;

[0021] Step 4: Obtain the risk resistance value of each cycle construction plan, and mark the cycle construction plan with the largest risk resistance value as the management execution plan;

[0022] Step 5: Use the management execution plan to construct the subway construction project in the next project management cycle.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The method of the present invention selects the cycle construction plan with the best comprehensive risk resistance ability through the comparative and comprehensive analysis of various risk types to construct the subway construction project, which helps to ensure the construction stability of the subway construction project;

[0025] 2. A subway construction building block, an expected data setting module, and an expected plan generation module are set up. The construction and dynamic update of the subway construction model are completed through BIM technology. Multiple construction plans are automatically generated periodically according to the expected data of various construction data, providing more construction plan selection spaces for the subway construction project. A plan risk resistance analysis module is set up to conduct a comprehensive risk resistance analysis on each cycle construction plan. By simulating the execution and performance of the cycle construction plan under this risk type through the subway construction BIM model, the predictability and pertinence of construction management are improved.

[0029] Step 1: Construct a subway construction BIM model and update the subway construction BIM model in real time.

[0030] Step 2: Every time a project management cycle passes, set the expected data of various construction data of the subway construction project in the next project management cycle.

[0035] Example 2: Refer to Figure 2 , a BIM-based subway construction project management system, including a subway construction building module, an expected data setting module, an expected plan generation module, and a plan risk resistance analysis module.

[0036] Subway construction building module: Build a BIM model for subway construction and update the BIM model for subway construction in real time.

[0037] To build a BIM model for subway construction, specifically: Collect all design drawings, construction drawings, etc. of the subway construction project, collect the actual situation and data of the subway construction site through on-site investigation, measurement, etc., select BIM software, create three-dimensional elements according to the drawings and data, adjust the position and size of the elements to match the actual construction site, and then build a BIM model for subway construction.

[0038] To update the BIM model for subway construction in real time, specifically: As the subway construction progresses, update the relevant information and data in the BIM model for subway construction in real time (adjust the elements in the BIM model for subway construction through corresponding sensors and on-site investigation, etc. In addition to the position and size, the attribute information of the components, such as materials, specifications, quantities, etc., also needs to be updated), to ensure that the updated BIM model for subway construction is consistent with the actual situation of the construction site.

[0039] Expected data setting module: Set the project management cycle (the project management cycle is a preset time period, and the length of the time period can be freely adjusted according to requirements. During the subway construction process, the project management cycle loops infinitely). Every time a project management cycle passes, set the expected data of various construction data of the subway construction project in the next project management cycle (construction data includes cost data, quality data, progress data, etc., and the expected data is the data that the construction data is expected to achieve in the next project management cycle).

[0040] Expected plan generation module: Input the expected data of various construction data into the subway construction BIM model (the subway construction BIM model generates multiple cycle construction plans, and each cycle construction plan is different. These differences may be reflected in multiple aspects such as construction sequence, resource allocation, construction methods, etc., but each cycle construction plan can ensure that the subway construction project meets the expected data of various construction data in the next cycle). The subway construction BIM model generates p cycle construction plans.

[0041] Set up the subway construction building module, expected data setting module, and expected plan generation module. Through BIM technology, complete the construction and dynamic update of the subway construction model, and automatically generate multiple construction plans periodically according to the expected data of various construction data, providing more construction plan selection space for the subway construction project.

[0042] Plan anti-risk analysis module: Obtain the construction plan anti-risk value of each cycle construction plan, mark the cycle construction plan with the largest construction plan anti-risk value as the management execution plan, and use the management execution plan to construct the subway construction project in the next project management cycle.

[0043] The method for obtaining the construction plan anti-risk value of the cycle construction plan is as follows: Determine a cycle construction plan, determine all risk types existing in the subway construction project (risk types include but are not limited to natural risks, technical risks, management risks, etc.), and then obtain the risk resistance values of each risk type. Sum up and take the average of the risk resistance values of all risk types to obtain the average risk resistance value Shdg. Match all risk types in pairs to form a resistance combination group, obtain the resistance combination value of each resistance combination group, sum up and take the average of the resistance combination values of all resistance combination groups to obtain the average resistance combination value Wdsj. Use the formula to obtain the construction plan anti-risk value Fygv of this cycle construction plan, where n1 is the average risk resistance coefficient, n2 is the average resistance combination coefficient, the value of n1 is 1.08, and the value of n2 is 1.19.

[0044] The method for obtaining the resistance combination value of the resistance combination group is as follows: Sum up the risk resistance values of the two risk types in the resistance combination group to obtain the comprehensive resistance value Bnkw. Calculate the difference between the risk resistance values of the two risk types in the resistance combination group and take the absolute value to obtain the resistance difference value Dprb. Use the formula to obtain the resistance combination value Haxe of this resistance combination group, where u1 is the resistance difference coefficient, and the value of u1 is 0.84.

[0045] The method for obtaining the risk resistance value of a risk type is as follows: Determine the risk parameters involved in a risk type, and input the cyclic construction plan and the risk parameters involved in the risk type into the subway construction BIM model (after the risk parameters involved in the risk type are input into the subway construction BIM model, the execution process of the cyclic construction plan will be affected by the corresponding risks. Taking natural risks as an example, parameters such as groundwater level and formation stability are involved). The subway construction BIM model conducts a simulation construction for a project management cycle. After the simulation construction is completed, collect the construction cut-off data of various construction data, obtain the construction inspection models corresponding to various construction data, input the construction cut-off data of various construction data into the corresponding construction inspection models respectively, and obtain the construction inspection values of various construction data. Set the high construction inspection value and the low construction inspection value (the high construction inspection value is greater than the low construction inspection value, and both the high construction inspection value and the low construction inspection value are preset thresholds). When the construction inspection value of the construction data is greater than or equal to the high construction inspection value, mark the construction data as satisfactory inspection data. When the construction inspection value of the construction data is less than or equal to the low construction inspection value, mark the construction data as disappointing inspection data. When the construction inspection value of the construction data is between the high construction inspection value and the low construction inspection value, mark the construction data as normal inspection data. Mark the total number of satisfactory inspection data as Sati, mark the total number of disappointing inspection data as Lhop, sum up and take the average of the construction inspection values of all normal inspection data to obtain the normal inspection value Hbzp, and use the formula to obtain the risk resistance value Eskt of this risk type, where v1 is the quantity influence coefficient, v2 is the normal inspection coefficient, the value of v1 is 1.38, and the value of v2 is 1.15.

[0046] Each construction data corresponds to an independent construction inspection model (for example, cost data and quality data respectively correspond to a construction inspection model). All construction inspection models are constructed based on neural network models. The difference between different construction inspection models lies only in the different training data. In this embodiment, taking cost data as an example, the construction process of the construction inspection model for cost data is disclosed: collect the construction cut-off data of multiple cost data (if it is to construct the construction inspection model for quality data, collect the construction cut-off data of multiple quality data), construct a neural network model, use the construction cut-off data of cost data as the training data of the neural network model, assign a construction inspection value to each training data, and the value range of the construction inspection value is (1.1 - 4.9). The larger the value of the construction inspection value, the better the performance of the cost data; the smaller the value of the construction inspection value, the worse the performance of the cost data (if it is to construct the construction inspection model for quality data, the larger the value of the construction inspection value, the better the performance of the quality data; the smaller the value of the construction inspection value, the worse the performance of the quality data). Divide the training data into a training set and a validation set according to the set ratio of 5:2, perform neural network iterative training on the training set and the validation set. After the training is completed, the construction inspection model for cost data is constructed.

[0047] Set up a risk resistance analysis module for the construction plan, conduct a comprehensive risk resistance analysis on the construction plan of each period, simulate the execution and performance of the construction plan of each period under this risk type through the subway construction BIM model, improve the predictability and pertinence of construction management, and select the construction plan with the best comprehensive risk resistance ability through the comparative and comprehensive analysis of various risk types to carry out the construction of the subway construction project, which helps to ensure the construction stability of the subway construction project.
