| 摘 要： | 以兰州市南北两山252条沟道内滑坡坍塌地质灾害的基本数据为基础,提出了滑塌率的基本概念,选择地震参数SA,流域汇水面积F,山地平均坡度A等参数为自变量,滑塌率L为因变量,利用多元回归的方法建立了适用于兰州及类似地区的滑塌率的数学模型.

| Abstract: | Using the landslide-collapse data from 252 valleys in the south and north mountains located in Lanzhou city,Gansu province,as an example,the paper suggests a new concept: landslide-collapse ratio(L).L is the function of the earthquake-parameter(SA),convergable water area of river basin(F),and average gradient of hillside(A).Using the method of multivariate linear regression,found a mathematical model of landslide-collapse ratio: a equation of multivariate linear regression,which is adapt to Lanzhou area and the alike. |
