Abstract: This paper presents the stability analysis results of a landslide in a soil slope in Liuzhou City. The mineral component at the slip surface were tested and factors that might contribute to the slope instability were evaluated. The landslide body was investigated by field and laboratory tests, back analysis and geological analogical methods. The factors of safety under normal and heavy rainfall conditions were able to be determined by using transfer coefficient method. Both the analysis and site reconnaissance results indicate that, the slope was stable under normal condition and was not stable under the heavy condition. Under continuous precipitation condition, the rate of slip would be accelerated.

Key words: Soil Slope Landslide, Back Analysis, Transfer Coefficient Method, Stability Analysis
