三门峡水库初步设计阶段的地质工作,由于缺乏准确的面积足够的地形底图,因而地质勘探工作不能按正常的程序进行。这就不得不以搜集资料的办法来满足设计的要求。在这里我首先要简单的谈一谈地形底图和地质工作关系这一个问题,其次再谈水库初步设计阶段究竟要做些什么地质工作,最后谈一谈将采取什么办法来完成水库的地质工作。 Geological work in the preliminary design stage of Sanmenxia Reservoir can not be carried out according to normal procedures due to the lack of accurate terrain topography. This will have to collect information to meet the design requirements. Here I will first briefly talk about the relationship between topographic maps and geological work, and then talk about what exactly geological work should be done in the preliminary design stage of the reservoir. Finally, I will talk about the measures we will take to complete the geological work of the reservoir .
