The H-shaped steel spacing and cement content are the key parameters of TRD (Trench cutting Re-mixing Deep wall), which directly affects the stress and displacement of the wall. To ensure the stability of the foundation pit, it is of great practical significance to optimize the steel spacing and cement content. Taking the urban utility tunnel in Hangzhou as the engineering background, the triaxial tests of cement-soil were conducted to study the influence of cement content on the strength of the cement-soil. The finite element model was established to analyze the deformation, stress distribution of cement-soil, and the spacing of H-shaped steel. Results show that the unconfined compressive strength and elastic modulus of cemented-soil increase linearly with the increase of the cement content in the range of 10%-25%. The tensile stress formed on the side of the foundation pit leads to the cement-soil damage, where there is the maximum horizontal displacement. According to the relationship between the cement content and the maximum H-shaped steel spacing, the optimized steel spacing and the cement content can be determined. The obtained conclusions can provide a reference for the similar engineering.
