Application Research Of BIM Technology In Construction Progress Management Of Gaoligongshan Tunnel

With the promotion of the “the Belt and the Road” strategy.China’s economic and trade exchanges with the relevant countries along the route have entered a new stage.The construction of railway infrastructure has also ushered in a major development.Railway traffic engineering is an extremely complex system engineering.Due to the long construction period,frequent cross-operations and narrow working faces,the project’s progress targets are often difficult to achieve in the implementation of railway traffic engineering projects.Due to the insufficiency of traditional project management technology and management software,it may lead to deviations in the construction schedule,even problems such as rework or increased construction period.Loss of control of the progress of the project will bring direct economic losses and even affect the quality of the project.The application of BIM technology in engineering projects can greatly improve the project manager’s progress control ability,reduce the risk of construction delay and improve the efficiency of schedule management,in addition creating huge economic and social benefits.However,there are only a few engineering projects in China that apply BIM technology.The application of BIM technology has not been popularized.The research on progress management based on BIM technology is relatively few,the engineering practice experience is insufficient,and the theoretical research is not mature enough.Therefore,it is necessary to explore the application advantages of BIM technology in project project schedule management.This paper first analyzes the traditional schedule management theory and BIM technology related theory.BIM technology can solve the problems of traditional schedule management,expand management concepts,strengthen management measures,and strengthen management level.Secondly,through the comparative analysis of BIM related modeling software,the Bentley series software is determined as modeling software.The construction schedule is prepared according to the work breakdown structure(WBS).Combined with the 3D model and the schedule,the secondary development technology is used to form a BIM technology-based schedule management system.the system has a virtual construction simulation function,which can pre-explore the problem of insufficient construction plan consideration under the traditional method.The management personnel can optimize and adjust the defects of the construction plan before the project construction,and realize the project’s Active control.Subsequently,the BIM technology is applied to the configuration optimization of construction resources.Through the combination of traditional network planning technology and BIM technology,the time-cost model is used to optimize resource allocation.BIM technology is used to model the project and perform virtual simulation construction to guide the progress and arrange and allocate resources for the project.Finally,taking the tunnel project as an example,the time-cost model is used to verify the optimal configuration of the project resources.The results show that the traditional network planning technology combined with BIM technology can effectively solve the resource allocation problem.The progress management system based on BIM technology realizes a series of applications such as BIM-based site layout,component digital processing,monitoring measurement,3D visualization and resource management in the process of progress management.It realizes the refined management and dynamic control of the project schedule.The research in this paper provides a reference for the construction management and practical engineering application of large tunnels under complex conditions based on BIM technology.
