摘要
河南丹江口水库在南水北调中线工程建成后,水库库容增加,库周地下水静、动压力急剧变化,岸坡岩土体抗剪强度降低,稳定性变差,形成50多处滑坡灾害地质体。文章以丹江口水库河南淅川段为研究对象,在充分分析库区地质环境背景的基础上,阐述了库区滑坡发育特征,从地形地貌、地层岩性、岩土体工程地质条件、构造特征和降水等方面分析了蓄水条件下库区滑坡的形成条件和诱发因素,并提出了库区滑坡的防治对策建议。
After the completion of the Middle Route of South-to-North Water Transfer Project,Danjiangkou Reservoir capacity increased accordingly,cause the rapid change of static and dynamic pressure of groundwater around the reservoir,the shear strength and stability of rock and soil on the bank of the reservoir decrease,resulting in numerous landslide disasters. This paper takes Xichuan section of Danjiangkou Reservoir in Henan Province as the research object,based on a full analysis of the geological environment background of the reservoir area,the development characteristics of the landslide in the reservoir area were described. The formation conditions and inducing factors of landslides in the reservoir area under the condition of impoundment are expounded from different aspects,including topography,formation lithology,condition of engineering geology,structural characteristics and precipitation,etc. At the same time,the countermeasures and suggestions of landslide prevention in the reservoir area are put forward.
