摘要

 Deep foundation pit dewatering is complex and geological disasters are easily caused by land subsidence in Yangtze River Delta region. The traditional analytic solutions of groundwater dynamics were difficult to meet the needs of simulation and calculation in the design of simulation, particularly hard to predict the land subsidence caused by dewatering. According to the control requirements of groundwater level,the layout of dewatering wells, discharge and land subsidence could be simulated and calculated by deep foundation pit dewatering and land-subsidence coupling model which coupled together with groundwater flow model and the soil stress-strain model.
