Numerical analysis of Deep Excavation Dewatering Induced Ground Subsidence

Abstract

Abstract: The mechanism of ground settlement due to foundation pit dewatering was analyzed. The mechanism of differential settlement as a result of change in effective stress and pore water pressure was discussed. The water and soil coupled model in ABAQUES was utilized in the simulation. The results of the analysis compared well with field observation. Additional parametric study indicates that ground settlement increases with increasing in foundation pit dewatering depth.
