Analysis of the Earth Surface Subsidence Caused By the Dewatering of Shenyang Subway in China

Abstract:

Abstract: 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 subwaywere analyzed by using Coupling System of Flow & Solid in FLAC-3D which is based on poroelasticity theory and consolidation theory, and preliminary results were obtained.
