| 中文摘要: |
| 在金沙江虎跳峡上游河段进行坝址比选研究中，发现金江—其宗河段河床中分布一隐伏的大型古堰塞湖。大量的地表测绘、勘探、岩土测试等工作表明：当时堰塞湖属于过水湖，位于红岩—上江河段，由1个或多个巨
型滑坡 （或崩塌） 堆积体组成，坝高不低于100m；河床湖相黏土最大厚度37.7m，土质软弱，透水性微弱，强度较
低。本文探讨了堰塞湖所处的地质环境以及河床地质对虎跳峡河段水电开发的影响，为坝址选择和枢纽建筑物方
案的布置提供依据。 |
| 英文摘要: |
| A massive hidden ancient landslide lake was found in the river bed of Jinjiang-Qizong reach in the Hutiao Gorge，Jinsha River，during the study on dam site selection for hydropower development. A lot of work including surface mapping，exploration，geotechnical testing and etc. showed that the overflow land?slide dam，with height no less than 100m，is composed of several giant landslides. There is a lacustrine clay layer in the river bed with maximum thickness of 37.7m，the characteristics of which are soft，weak
per eability and low intensity. In this paper，the complicated geological environment of forming the land?
slide lake and the effects of lacustrine clay to dam site selection，design and building are discussed. |
