Finite Element Analysis of the Construction of the Subway Tunnel Test Section below through the Railway Bridges

Abstract:

During the construction of city subway, it often needs to cross under the existing buildings, which will have some influence on these buildings. The article, taking the engineering of subway tunnel in Harbin city for example, uses finite element analysis software to simulate the dynamic excavation of the tunnel, and combines with the measured data of actual monitoring, analyzes the primary support structure stability in the process of tunnel excavation. Finally it draws the conclusion that the stress and displacement near the working face change greatly, the springback displacement of tunnel bottom is big, fracture surface near the entrance of the hole tends to be stable with the excavate of the working face.
