潘家口水利枢纽是从上、下两个坝址中比较后选定下坝址的。这两个坝址,在工程地质勘察和施工阶段都进行了物探工作,尤其是地震法探测做得较多,也收到了较好的效果。从潘家口工程实践中使我们认识到地震探测是一项又快又经济,同时又能较客观地反映实际的探测方法。现将我们在这方面的工作成果介绍如下。 Panjiakou Water Control Project is selected from the upper and lower dam sites after the dam site comparison. Both of these dam sites conducted geophysical surveys during the period of engineering geological survey and construction. In particular, the seismic method has done more exploration and received better results. From Panjiakou engineering practice, we have realized that seismic exploration is a fast and economical method, and at the same time it can objectively reflect the actual exploration methods. Here is the result of our work in this area as follows.
