Abstract :
Construction of metro in many cities of China is in the ascendant. But frequently, many accidents happened when the pits are excavated especially in the area where the geological condition is not good such as the alluvial flat, and also, the ground deformation caused by excavating would influence the near building. Verified with the pit excavating of a city metro, both FLAC3D numerical simulating and field monitoring are used to analyze the construction safety. Further, the results of two method are compared to validate the veracity of numerical simulation and the applicability of the Mohr-Coulomb rule. And then the method can be used in other subway construction projects, so as to provide a important basis for the metro designing and construction with similar geological condition.
