一、概述水利水电工程地质勘察的工作深度、工作量和布置原则等,除与地形地质条件的复杂程度有关外,还与水利水电枢纽工程的等级、规模有很大的关系。建国以来,我国已兴建了八万多座中小型水利水电工程,今后仍有大量的中小型水利水电工程需要建设。据水资源普查资料统计,我国可开发利用 I. General Overview The work depth, workload and layout principles of geological survey of water conservancy and hydropower projects have a great relationship with the scale and scale of hydropower projects in addition to the complexity of topographic and geological conditions. Since the founding of the People’s Republic of China, more than 80,000 small and medium-sized water conservancy and hydropower projects have been built in our country. In the future, there will still be a large number of small and medium sized water conservancy and hydropower projects that need to be constructed. According to the census data statistics, China can develop and use
