APPLICATION OF 3D COUPLING MODEL OF SEEPAGE AND STRESS FOR SIMULATING DEEP FOUNDATION FITS DEWATERING

FENG Xiao-la1,XIONG Wen-lin2,HU Tao3,SHEN Jiang-tao3(1.Engineering Department,China University of Geosciences,Wuhan 430074,China;2.Department of Roadway and Bridge Engineering,Hubei Communications Technical College,Wuhan 430079,China;3.Wuhan Research Institute of Construction Engineering,Wuhan 430022,China)  
Based on a literature survey,the application of coupling model of seepage and stress in rock and soil masses for simulating deep excavation dewatering is studied. Dewatering engineering of the passage under street of the Zhongshan public square is taken as an example and 3D finite element method is used to simulate the dewatering case. Through the 3D finite element analysis,the three-dimension numerical simulation method can be applied to study impervious curtain,anisotropy and pressurization—pressure that is hard to solve in practical engineering conditions. Therefore,numerical simulation technique is useful in dewatering excavation and ground settlement computation.
