摘要

西藏满拉水利枢纽坝址位于高海拔、高地震烈度区 ,其左岸上、下游均分布有规模较大的坍滑体 ,影响边坡稳定和水工建筑物的安全运行。为此对左岸坍滑体进行了专门的勘察和试验研究 ,并且在坍滑体上布置变形监测网 ,在施工期和水库蓄水期及运行初期对坍滑体的地面变形 ,地裂缝张开度和深部分层水平位移进行了监测。今后对上、下游坍滑体继续进行变形监测 ,以便对可能产生的塌滑及时作出预报 ,保证满拉水利枢纽长期安全运行是很有必要的。
The Manla Hydro-Junction Project in Tibet is located on the high plateau area with high earthquake intensity. There are large-scale landslides existing within up-and down-streams near the hydro-Junction site on the left bank,which have a potential threat to the project.Therefore,a special investigation and an experimental test has been done on the landslides on left bank and a deformation monitoring network has been set up and covered the landslides. The deformation data were collected during the reservoir construction and imponding and early operation stage of the project. Analysis of the deformation data permitted us to predict the possible slip of the landslides. The reuslt is very important for the safety of the Manla Hydro-Junction.
