一、前言我省已建成的水库有九千九百多座,土坝有上万座,它们的绝大多数是碾压式土坝,且在施工填筑中,都难于按设计的质量要求来控制。因而,土坝虽已建成并运用,但它的竣工质量是不够清楚的。故从六十年代开始,对已建成并运用多年的土坝进行勘探、试验并验算坝坡的抗滑稳定性,就成为我

I. INTRODUCTION There are more than 9,900 reservoirs built in our province, and there are tens of thousands of earth dams. Most of them are roller compacted earth dams, and it is difficult to meet the design quality requirements in construction and construction. To control. Thus, although the earth dam has been built and used, the quality of its completion is not clear enough. Therefore, since the 1960s, it has become me to survey and test the earth dams that have been built and used for many years, and to check the anti-sliding stability of the dam slopes.
