Abstract

Abstract: Slope safety factor and landslide probability can be reflected by landslide’s influential factors. In this article, a function describing the relationship between safety factor and landslide probability was presented. The function between safety factor and influential factors was analyzed using the limit equilibrium method, and the relations between influential factors and landslide probability were then obtained using logistic regression model. The landslide probability of 38 ionic-type rare-earth ore slope in south Jiangxi Province were obtained by using SPSS software, and the fitted relation between safety factor and landslide probability was hence deduced. The fitted function was verified correct by engineering specification.

Key words: landslide probability, safety factor, landslide's influential factors, logistic regression model, SPSS
