LAND DEFORMATION CAUSED BY DEWATERING OF FOUNDATION PIT
The dewatering of foundation pit can cause the seepage outside and inside the foundation pit, and result in the changes of groundwater, earth pressure and mechanical properties, and directly affect the earth pressure acting on supporting structures.
It analyzes design of deep foundation pit precipitation of one building, and introduces and analyzes how to layout precipitation well point & works and influencing to around environment in construction of light well point precipitation, the result indicates effect is good.
The artificial large-diameter well drainage scheme was very successfully applied in Sanya World Trade Centre deep foundation pit in the paper. The success of the project not only have proved that the methods is feasible but also have provided a new way for Sanya area foundation pit drainage.
