The decompression and discharging of underground in deep foundation pit construction in soft soil area are easy to cause the land subsidence and other environmental geological problems.Using the deep foundation pit engineering in Shanghai subway station,this paper,analysis the land subsidence dynamic characteristics after setting the waterproof curtain and artificial recharge in shallow aquifer and other methods,and discusses the watertightness and laying depth of pit support structure,and studies the technical requirements of artificial recharge and information monitoring and their integrated applications.The above mentioned methods are to the benefit of preventing and controlling the land subsidence in deep foundation pit engineering.
