| Abstract: | In this paper,the routine design method is reviewed for retaining structure ofdeep excavation insoft soils.An analysis has been made forthe influence of the wall rigidity on the earth pressure distribution.The effect of underground water on the lateral pressure,as well as the determination of design parametersand the finite element method used in supporting structure design are discussed.At last,the safetyevaluation on supporting structure is proposed. |
