Numerical Simulation of Shield Tunnel Crossing Masonry Structure Building with Various Degrees

Abstract:

Considering the interaction of building-soil-tunnel, the strip foundation masonry building vertical crossed by shield tunnel was simulated by 3D MIDAS/GTS software, and the stress and deformation of building before and after shield machine through the building were analyzed. The results showed that: the deformation and the force are different with different angles through the building; with the angle increases, the central base settlement slightly increased; the maximum overall differential settlement reached at 45 degrees; the maximum shear strain is reached when the machine is completely through the building; with the increase of crossed degree from 22.5 degrees, 45 degrees, 67.5 degrees to 90 degrees, the maximum shear strain of wall increases; the plastic zone of wall is mainly at the top cross position in the wall.
