الوصف: In the process of analyzing the stability of loess slope, determining the value of strength parameter c and φ is a much more complex problem, and there is not mature and systematic method. In this paper, the inverse analysis of the value c and φ in Shanxi Jijiayuan cutting loess slope, about 51.6m, by bishop method and Spencer method based on the statistical strength indexes. To analyze the stress of the slope used finite element and compare the inverse result and test data. The result indicates the value of c will control the stability of slopes in Q3 layer, and the value of φ will control the stability of slopes in Q2; the inverse result is close to the result with direct shear test when the moisture content is sample’s plastic limit moisture content. we can select strength parameters obtained though the direct and quick shear under the conditions that the soil sample’s moisture content is plastic limit moisture content for evaluation the slope stability. For the high slope, it should be cautious to select the φ in the lower part.
