摘要
三峡库区滑坡与地质环境相关,并受库水与降雨等诱发因素的影响,研究滑坡变形与诱发因素之间的关系,有助于为滑坡预测预报提供合理的判据。以老蛇窝滑坡体为例,结合该滑坡地质结构特征与监测数据,首先采用K均值方法聚类,将滑坡变形过程定性划分为3个阶段;然后通过关联规则方法研究影响因素与滑坡位移之间的关系。结果表明:滑坡所处的变形阶段与降雨特征因子和库水位变化有密切的相关性。
The landslide in Three Gorges Reservoir area is related to geological environment and influenced by the inducing factors of reservoir water and rainfall,etc.The research on the relation between landslide deformation and inducing factors is helpful to providing prediction and forecasting basis of landslide.Laoshewo landslide is taken as the study object with combination of its geological features and monitored data on landslide evolution,the landslide deformation process is divided into 3 stages qualitatively by k-means clustering;and then,the relation between landslide displacement and influential factors is researched by association rules.The result shows the deformation stage of landslide has a close relation with rainfall and water level of the reservoir.
