摘要: 为了给安全系数和滑坡概率的相互转化提供理论依据,分析滑坡影响因素与安全系数、滑坡概率的函数关系,得出安全系数与滑坡概率之间的函数关系。采用极限平衡法分析滑坡影响因素与安全系数的函数表达式;应用逻辑回归模型分析滑坡影响因素与滑坡概率间的函数关系;结合赣南38个离子型稀土矿边坡实例,应用SPSS软件,求解各边坡的滑坡概率,并得出滑坡概率和安全系数的拟合函数。选取10个边坡实例,同时采用边坡安全系数工程规范对拟合函数进行检验,结果表明了函数关系的准确性。

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
