Abstract: A landslide occurred at a cut slope left side of YiyangZhanjiang Rail Line between Station K331+332 and +600. This paper characterizes the factors that might contribute to the sliding. The condition of the current slope is analyzed by the engineering geology and landslide transfer methods. It is concluded that the current slope is instable and mitigation is necessary. The remediation scheme is focused on a new retaining structure, diverting the surface runoff water as well as providing proper drainage to the groundwater. During the design, proper sampling and testing work are necessary in order to quantify the engineering properties of surrounding soil and rock materials.
