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。
Slope safety factor and landslide probability can be reflected by landslide^ s influential factors. In this ar-ticle ,a function describing the relationship between safety factor and landslide probability was presented. The func-tion between safety factor and influential factors was analyzed using the l im it equilibrium method,and the relations between influential factors and landslide probability were then obtained using logistic regression model. The land-slide probability of 38 ionic-type rare-earth ore slope in south Jiangxi Province were obtained by using SPSS soft-ware, and the fitted relation between safety factor and landslide probability was hence deduced. The fitted function was verified correct by engineering specification.
