Abstract

This paper presents a case study of river wall reinforcement by soil–cement columns using deep cement mixing method. The study includes the selection of the best method among alternatives using alternative hierarchy process, the description of the construction technique, the evaluation of the engineering properties of soil–cement, and the finite element simulation of soil–cement and wall performance. The results show that ground improvement by cement admixed clay with sheet pile facing was the most suitable method for this case. The stress–strain behavior of soil–cement was obtained from triaxial compression tests with loading and unloading cycles on laboratory remixed samples. The parameter optimization indicated that the Mohr–Coulomb Model was better than the UBC Sand Model and the Hardening Soil Model for simulating soil–cement behavior. The 3D finite element analysis using the optimized parameters accurately predicted the river wall response under different stress path.
