In excavation work on soft ground, the soil improvement method by buttress typed deep cement mixing walls is employed in order to prevent the earth retaining wall displacement. In the design of earth retaining structure, it is important to evaluate precisely the prevention effect of earth retaining wall displacement. In this paper, based on field measurement of earth retaining wall displacement and FEM analyses on buttress shapes and ground rigidity, the evaluation method of the prevention effect on earth retaining wall displacement with Winklerian model calculation is presented.
