Abstract

Abstract:

With the rapid development of urban buildings and metro projects, the situation of buildings adjacent to metro structures is common. As a result, it is very important to estimate the influence of building construction on safety of metro structure. A 2D and 3D numerical model of a construction project in Xiamen adjacent to existing metro structure are established by finite element software MIDAS/GTS. And then the influence of the building construction on internal force and deformation of main metro station structure, subsidiary structure, shieldbored section and mined section are studied. The study results show that the influence of building construction on adjacent metro structure can be controlled effectively.

Key words: main metro station structure, subsidiary structure, shieldbored section, mined section, numerical simulation, displacement of structure, internal force of structure
