Abstract: The shape and location of the sliding surface was confirmed by engineering investigation and displacement monitoring of the landslide of Jiao-Liu Railway project, and the thrust transfer coefficient method was performed to analyze the stability of the landslide, in which the influence of groundwater was taken into account. The strength indexes of soil on sliding surface, cohesion c and angle of internal friction φ, were obtained by back-analysis based on least-squares method. It shows that the method can analyze quantitatively the contribution of dewatering to safety factor of the landslide, so that the retaining structure is designed economically. The strength index that solved by multi-sections’ data represents the overall character of the soil on sliding surface, which reduces the randomness influence of tested data. The method and the conclusion can be used for reference by similar projects.

Key words: landslide, stability, strength index, groundwater, dewatering
