白家包滑坡变形影响因素定性及定量分析
Qualitative and Quantitative Analysis of Deformation Influencing Factors of Baijiabao Landslide
摘要
Abstract
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 accumulative 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 analysis results.The results show that the quantitative analysis of the main influencing factors of Baijiabao landslide is consistent with the result of qualitative analysis;the accuracy rate is 84.62％,so sa to show that the model is certainly applicable;and the methods can also provide a reference for relevant researches.关键词
