Abstract：The constant thickness steel cement-soil wall constructed by TRD method is a new type of retaining structure. It has already widely used in deep excavations. Because of the difference in stiffness between cement-soil and steel, complex interaction between the two materials exists in the steel cement-soil wall. The current engineering practices lack theoretical analysis and calculations. Based on the typical Shanghai soft soil strata, 3D “m” method is employed to analyze the interaction between cement-soil and steel, and the deformation and bearing characteristics of the constant thickness steel cement-soil wall is introduced, focusing on displacement, distribution of bending moment and local shear resistance. Those issues are also addressed for the design of steel cement-soil wall. Finally, the calculated and in-situ measured lateral displacements of wall are compared.
