The landslide is located on the left hank of Tuojiang in Chengdu and deep digging was to he done at its front edge. Surveys and investigations were made to reveal the landslide's features. Combined with engineering influences, its stability was evaluated. According to the calculation results and the engineering layout, multi row pile, pile plate and frame beams were used for the engineering treatment. The analysis resuhs of deformation monitoring data show that the treatment effect is obvious.
