河谷是水电勘测的对象,也是其他工业建设的主要场所。河谷工程地质的研究成果,将为工程建设提供坚实的依据。但是与水电开发有关的河谷卫程地质问题,重要而急待解决的河流侵蚀与河床深厚覆盖层,以及第四纪冰川对河床的加积等问题,则很少研究。而大型水电工程实践证明,没有这方面的勘测研究,水电建设几乎是不可能的。 近年来,我院对大渡河进行了系统的水电规划工作,提出了梯级开发方案,完成了许多勘探工作量,其中钻探累计进尺达七万米,洞探达七千四百米,基本掌握了河谷工程地质的规律性。
River valley is the object of hydroelectric survey, but also the main place for other industrial construction. The research results of valley engineering geology will provide a solid foundation for the construction of the project. However, there are few studies on issues such as geological and geological problems in the valley related to hydropower development, important and urgent river erosion and deep bed cover of riverbed, and accretion of riverbed by Quaternary glaciers. The large-scale hydropower engineering practice has proved that without this research, hydropower construction is almost impossible. In recent years, our hospital conducted a systematic hydropower planning of the Dadu River, proposed a cascade development program and completed many exploration workloads, of which drilling footage reached 70,000 meters and exploration holes reached 7,400 meters, basically mastered Geological regularity of valley engineering.
