Abstract: The vegetation of the side slopes of a memorial museum in Pingyang County was destroyed and topsoil was eroded due to the adjacent highway and building constructions. The landslide is easily triggered by the adverse factors such as precipitations. The factors of safety of these slopes are analyzed by the Spencer Method and the results are compared with the code requirement. A comprehensive slope stability method: concrete gravity wall + sliding resist caisson + measures of collecting and diverting surface runoffs are proposed based on the site conditions and local landslide treatment experience.
