INFLUENCE OF INITIAL STIFFNESS OF CONTACT ELEMENT ON DEFORMATION OF DEEP FOUNDATION PIT IN SOFT SOIL
接触元初始刚度系数对软土深基坑变形的影响分析

The Goodman element is used to simulate the interaction between soil and structure. Taking the deep foundation pit of Huangpu river walking tunnel as an example, the influence of stiffness of Goodman element on displacement of wall and surface settlement is analyzed with finite element method. This provides a basis for the choice of stiffness coefficients on numerical calculation of soft soil foundation pit and informationalized construction.
