摘要
滑坡是一种对人们的生命和财产安全造成严重威胁的地质灾害,历史上三峡库区就是一个滑坡多发区,虽然该区域滑坡的研究由来已久,但大多是对库区内某个或某些滑坡进行研究,很少系统地研究它们.本文综合分析结果显示滑坡的产生是一个综合效应,受内因、外因的共同影响,其中内因包括地层、地貌和构造等地质环境要素;外因包括暴雨、地震、库水作用等可变自然因素和人为因素.只要摸清了滑坡的成因机制、变形过程,它们也是可控可防的.
The landslide is a kind of geological disasters which will cause a serious results to the public＇s life and properties. The area of Three Gorges reservoir is a landslide often happened area historically,researches on landslide for the region has a long history,but most of the examinations are for some or some of the landslide,few of them study on the whole area systematically. It shows the occurrence of landslide is a result of comprehensive effect,influenced by the internal cause and external cause. Internal factors which include the stratum,landforms,structure and other geological environment factors; External factors which include heavy rain,earthquake,role of reservoir water and other variable natural factors and human factors. As long as to find out the formation mechanism and the deformation process of landslide,they also can be controlled and prevented.
