西乡盆地小型水电工程地质环境适宜性评价

Geological Environment Feasibility for the Construction of Small-scale Hydropower Project in the Xixiang Basin of Shaanxi Province

通过现场调查和理论分析，研究了拟建的西乡盆地乔山水电站工程建设区地质环境条件及地质灾害类型、分布、规模，分析了地质环境条件对水电工程的影响及水电站建设和运营过程中对地质环境条件的影响，探讨了西乡盆地小型水电工程地质环境适宜性，提出了地质灾害防治措施建议。作者认为，从地质环境条件看，西乡盆地建设小型水电工程是基本适宜的。

On the basis of site investigation and analysis, the type, distribution, scale of geological hazards of the planned Qiaoshan hydropower station and their influence on the construction of hydropower station as well as the influence of hydropower station on geological environment are studied, and the geological environment feasibility for the construction of small-scale hydropower project in the Xixiang basin is discussed. Mean- while, suggestions for geological hazard prevention are given. It is concluded that from the viewpoint of geological environment, the construction of small-scale hydropower station in the Xixiang basin is feasible basically.
