LAND DEFORMATION CAUSED BY DEWATERING OF FOUNDATION PIT

Studied on the phreatic aquifer, the mechanism of the land subsidence and the characteristics of soil compaction due to dewatering were analyzed. Based on the viscoelastic stress-strain relationship with the consideration of soil-pore water reaction, the models of land subsidence and horizontal displacement due to dewatering of foundation pit were proposed, and the analytical solutions to the models were obtained.
