Effects of Foundation Pit Dewatering on Load-bearing Capacity of Soil Body around the Pit

It is proved that pit safety has a close relationship with foundation pit dewatering.In order to find out the relationship between foundation pit dewatering and load-bearing capacity of soil body around the pit,a vast amount of original position monitoring work has been engaged.Based on the groundwater level monitoring data,load tests by pressure bearing plate,and static cone penetration test,the empirical mathematic models of the variations of groundwater level and load-bearing capacity of soil body around the pit were set up after foundation pit dewatering. The model construction process as well as application effects have been introduced in our paper.

Key words:foundation pit,foundation pit safety,foundation fit dewatering,load-bearing capacity of soil body,groundwater level,empirical mathematic model
