确定库岸滑坡变形的主要影响因素,可以为库岸滑坡的防治提供更有效指导.本文以三峡库区白家包滑坡为研究对象,首先收集了白家包滑坡监测资料以及三峡库区库水和降雨资料;然后定性分析白家包滑坡累积位移变形阶段及特征,将该滑坡累积位移主要影响因素分为三类：降雨和库水的共同作用;主要为降雨作用;主要为库水作用;最后利用相对库水位、降雨量和累积位移相关系数,分别建立降雨和库水位对滑坡位移影响系数模型,定量计算出该滑坡变形主要影响因素,与定性分析结果进行对比.研究结果表明,白家包滑坡位移主要影响因素定量计算与定性分析的结果吻合度较高,准确率为84.62%,模型具有一定适用性,其方法也能为相关研究提供参考.

英文摘要：

To determine the main influencing factors of reservoir bank landslide deformation can provide more effective guidance for the prevention and control of landslide. So in this paper, the Baijiabao landslide in the Three Gorges reservoir area is taken as the object of study. First,the monitoring data of Baijiabao landslide and the reservoir water and rainfall data of the Three Gorges reservoir area are collected. Then, the accumula- tive displacement and deformation characteristics of Baijiabao landslide are analyzed qualitatively. The main influencing factors of cumulative displacement are divided into three categories： A, collective effect of rainfall and reservoir water; B, mainly for the effect of rainfall; C, mainly for the action of reservoir water. Finally, the influence coefficient model of rainfall and reservoir water level on landslide displacement is established by using the relative reservoir water level, rainfall and cumulative displacement correlation coefficient. The main influencing factors of landslide deformation are calculated quantitatively and compared with qualitative analy- sis results. The results show that the quantitative analysis of the main influencing factors of Baijiabao land- slide is consistent with the result of qualitative analysis; the accuracy rate is 84.62%, so sa to show that the model is certainly applicable＇s and the methods can also provide a reference for relevant researches.
