叶巴滩水电站位于四川白玉县与西藏贡觉县境内的金沙江干流上。丁巴滑坡位于坝址上游约6.5km的金沙江左岸,为一土质牵引式新滑坡。滑坡呈不规则弓形,前缘位于江边高程2740m,后缘最高点高程约2910m,滑坡体纵向长约300m,前缘宽约550m,物探测试滑坡体平均厚度25m,滑坡体体积约200万m3。该滑坡距坝址区较近,对滑坡进行稳定性研究,评价其在围堰挡水及水库蓄水后对工程的影响十分重要。
Yebaotan Hydropower Station is located on the main Jinsha River in Baiyu County, Sichuan Province and Gongjue County in Tibet. Dingba landslide is located on the left bank of the Jinsha River about 6.5km upstream of the dam site, and is a soil-dragged new landslide. The landslide is irregularly shaped. The front edge is located at an elevation of 2740m on the waterfront with an elevation of 2910m at the highest point of the trailing edge. The vertical length of the landslide body is about 300m. The width of the front edge is about 550m. The average thickness of the geophysical test landslide body is 25m. . The landslide is close to the dam site. It is very important to study the stability of the landslide and evaluate its impact on the project after the cofferdam is blocked and the reservoir is impounding.
