As the available space on the city's ground gradually decreases and traffic congestion occurs frequently, it is urgent to develop underground space and vigorously develop tunnel traffic. However, there is currently no suitable method for virtual construction simulation of tunnels. It constructs a measurement crib based to BIM technology platform, and has cross-tested and applied to the geometric model of tunnel construction tecniques. This paper shows that the experimental test results suggest that the algorithm proposed in this is able to quickly and to efficiently solve the problem of collision detection efficiency in quantitative global and local detection in the virtual simulation space, which is also very helpful to improve the execution speed of large large-scale projects. This paper combined with the virtual construction algorithm based on the tunnel segment assembly proposed in this paper, proposed a BIM-based tunnel parameterization design method, which achieved the goal of fast and accurate tunnel parameterization design. Based on the integrated technology of BIM modeling and engineering calculation, this paper analyzes the influence of construction parameters on the additional response of underground pipelines and strata caused by tunnel construction. The results show that the support pressure has a greater effect on the settlement of the underground pipeline and the surface, and the support force of the palm face has a greater effect on the forward bulge. When the tunnel is parallel, the maximum shear stress in front of the excavation face increases with the support pressure Increase, the rear decreases as the support pressure increases.
