| Abstract: | Based on the analysis of the deformation and the failure of the retaining walls and the soil mass of deep excavation in soft clay,coupling with the analysis of failure reasons for excavation,the conception of corner effect is presented in this paper,which is always neglected in the design and construction of deep excavation in soft clya.This paper analyzes the formation methanism and the composite characters of the corner effect of deep excavation,and discusses its influencec on the stability of excavation,and its treatment measures as well. |
