Abstract

Geomechanical analysis of surface subsidence development due to construction of deep underground station is presented. The station is a typical pylon structure, which is usually used during construction of the latest subway station in Saint Petersburg. Numerical modeling of step-by-step underground station construction is conducted. The results of the numerical analysis allow to predict the magnitude of surface settlement and understand the wide of settlement trough.
