工程地质勘察是水利水电建设的基础工作,其任务是查明工程建设地区的工程地质条件,为规划、设计及施工提供可靠的资料。规划选点与坝址选择是工程决策的重要环节,坝址地质条件的优劣直接关系到水利水电枢纽设计与建设能否顺利进行。但在规划选点与坝址比较期间又不可能进行大量的勘测工作,这就需要我们运用以往的实践经验,分析研究一切
Engineering geological survey is the basic work of water conservancy and hydropower construction. Its task is to identify the engineering geological conditions of the project construction area and provide reliable information for planning, design and construction. The selection of planning points and dam site is an important part of engineering decision-making. The geological conditions at the dam site are directly related to the design and construction of the water conservancy and hydropower hub can be smoothly carried out. However, it is impossible to carry out a great deal of surveying work during the comparison between the planned election site and the dam site, which requires us to use the past practical experience to analyze and study everything
