卅年来,我们虽然修建了不少水库,取得了很大的成绩。但是,由于种种原因,不少水库至今仍未达到设计效益,其中,不少是由于土坝质量问题影响了工程效益的发挥,因此,病险库的处理问题被提了出来。为了切实做好这一工作,首先必须对已建土坝进行质量检查,查清其所存在的主要问题,提出切实可行的处理办法,使问题得到解决,以发挥工程应有的效益。过去我们在对土坝进行质量检查时,常采用钻机钻孔和人工竖井两种办法。经过总结对 In the past few years, although we built a lot of reservoirs, we have achieved great success. However, due to various reasons, many reservoirs have not yet reached the design benefits so far. Many of them are due to the quality of the earth dam affecting the performance of the project. Therefore, the handling of the dangerous bank was put forward. In order to do a good job of this work, we must first conduct quality inspection on the earth dam that has been built, find out the main problems that exist, and put forward feasible measures to solve the problems so as to bring the due benefits of the project into full play. In the past when we carried out quality inspection on earth dams, drilling rigs and artificial shafts were often used in two ways. After summing up
