Analysis of the earth surface subsidence caused by dewatering of northeastern subway in China

During excavation in deep foundation pit, the deformation of soil and earth surface caused by engineering dewatering is an important factor to affect engineering safety. In this paper, according to the data provided by the detailed survey report of route 1 subway in Shenyang, the subsidence laws of the ground and around buildings caused by the dewatering of route 1 subway were analyzed by using Coupling System of Flow & Solid in Rock Failure Process Analysis (abbreviated as RFPA) which is based on poroelasticity theory and consolidation theory, developed by CRISR, Northeastern University, and preliminary results were obtained.
