摘　　要：对于水利工程来讲,必须要对地质问题予以高度重视。如果在设计施工的过程之中没有能够充分考虑和处理地质问题,那么就可能带来非常严重的后果。结合具体案例,针对贵州省某水库工程河床坝基开挖揭露的断层,结合所开展的专门性工程地质勘察研究,通过综合试验和分析成果对坝基岩体进行了工程地质分类,探讨了对重力坝建基面的影响,从而得出了岩体建坝的可行性。For hydraulic engineering,geological problems must be highly valued.If geological problems are not fully considered and handled in the process of design and construction,it may bring about very serious consequences.In view of the faults uncovered during the excavation of the riverbed dam foundation of a reservoir project in Guizhou Province,the rock mass of the dam foundation is classified by comprehensive test and analysis results in combination with the special engineering geological investigation and research carried out in this paper.The influence on the foundation surface of gravity dam is discussed,and the feasibility of dam construction by rock mass is obtained.
