摘　　要：以国内部分重点水电工程为例,对我国水电工程建设中坝基岩体质量分类、主要岩石力学参数的选取、大坝建基面的确定及弱风化岩体利用情况进行总结与分析;指出简化的坝基岩体多因子分类、岩体力学参数的提取与岩体质量分类相配套、按等值线提取岩体物理力学参数并动态确定大坝建基面的方法,应是水电工程坝基工程岩体研究的发展趋势。Some key domestic hydropower projects as examples, the article summarized and analyzed the dam bedrock quality classification in hydropower projects of China, selection of the main parameters of rock mechanics, determination of the base surface of dam, as well as the situation taking advantage of weekly weathered rock. The article maintained that a new approach should be the trend of research and development of the dam foundation rock in hydropower projects. This method is to simplify multi-factor classification of dam base rock, make the extraction of rock mechanics parameters and rock quality classification to form a complete set, extract physical and mechanical parameters by contour as well as dynamically determine the surface of dam bedrock.
