Abstract: The surrounding soil mass was disturbed by the construction of urban shallow buried tunnel, then there was the differential settlement and collapse of surface, in which the influence of its stress pass was obvious, meanwhile the ground traffic and architectures were also disturbed. Therefore the soil layer deformation induced by the stress path of tunnel construction was studied by using ANSYS to simulate the excavation sequences of different tunnels. Based on the tunnel engineering in Wuhan, the deformation of disturbed soil was analyzed and its regularity was obtained.
