Abstract

Landslide is the inevitable geological hazard in all kinds of linear engineering. Based on the principle of fuzzy transformation and the principle of maximum membership degree, a method for the landslide stability was established. The indexes of landslide macroscopic deformation and slope characteristics were chosen as the evaluation factors, which were divided into stability, basic stability, instability and extreme instability. The weights were determined according to the scoring of the present experts. Landslide of the railway station was evaluated by this method, the result is [0.20, 0.23, 0.32, 0.24]. The stability level is unstable. The accuracy of this method is proved by comparing with the standard method.
