九甸峡水库区滑坡、滑塌、卸荷变形现象分布很普遍。它的发生是地形地貌、岩性与地质构造、水文地质条件及水文、气象等综合作用的结果 ,尤其与地质构造之间有着密切的关系。以地质构造为主要表征的岸坡地质结构是库岸稳定与否的决定因素 ,暴雨、洪水、地下水及蓄水后的库水浮托力、河水位的骤然消涨等是库岸失稳的诱发因素 ,查清库区地质构造的发育分布特征 ,对于准确评价库岸稳定 ,合理估价水库效益有重要的实际意义。
The distribution of landslides, slump and unloading in Jiadianxia reservoir area is very common. Its occurrence is the result of the combined effect of topography, lithology and geological structure, hydrogeological conditions and hydrology and meteorology, especially with the geological structure. The geological structure of bank slope is the decisive factor of the stability of bank and bank, which is mainly characterized by geological structure. The sudden drop of heavy rain, flood, underground water, Inducing factors and ascertaining the distribution characteristics of the geological structure in the reservoir area are of important practical significance for accurately evaluating the stability of the reservoir bank and valuing the reservoir benefits reasonably.
