Research On Construction Simulation And Management Of Haicang Tunnel Based On BIM Technology

As the country vigorously develops transportation infrastructure construction,there are more and more tunnel construction projects.The traditional tunnel construction management has the disadvantages of scattered information,complicated personnel allocation,and untimely processing of quality and safety issues.BIM(Building Information Model)technology has the characteristics of visualization,simulation,optimization,and collaborative informationization,which can improve the tunnel construction management level.In this paper,BIM technology is applied in the construction process of Haitang Tunnel,and BIM visualization 3D modeling,construction process simulation and construction collaborative management research are carried out.The main research work and results of the thesis are as follows:(1)The three-dimensional visual BIM model of Haitang Tunnel dividing the surrounding rock grade was established by Autodesk Revit software.The collision check was performed based on the three-dimensional model of the tunnel,and the two-dimensional planar design was reviewed.(2)Implementing the construction site visualization technology through the visual tunnel BIM model.The tunneling CRD method excavation simulation was carried out using Autodesk navisworks software.At the same time,the 4D time schedule and 5D cost schedule simulation of tunnel construction were carried out by Guanglianda BIM5 D software.(3)Using BIM technology for tunnel construction management,using Guanglianda BIM5 D three-end one cloud to establish a tunnel project construction management platform,information-based collaborative management tunnel construction information model,quality safety,and schedule cost.
