在全面搜集地质测绘与勘探、系统测年、岩土试验 等大量勘察资料的基础上，系统阐述了金坪子滑坡的地质背景、滑坡分区及特征，分析研究 了金坪子滑坡的形成机制及金沙江金坪子河段河谷地貌演化过程，明确了滑坡主体位于金沙 江古河槽中且处于稳定状态的结论，为乌东德梯级开发的确立和坝址比选奠定了基础，也为 乌东德梯级河段乃至金沙江流域河谷发育史的研究积累了重要技术资料，其成果与经验可为金沙江流域水电梯级开发中的类似工程所借鉴。

The Jinpingzi Landslide, located in the downstream of the Wudongde Hydro -power Station about 900 m on Jinsha Rive r,was estimated 0.62 billion m3 by using remote sensing technology. The st ability, the movement trend and the possibility of the failure form are the key geological issues tha t have to be solved. On the basis of the geological mapping, drilling and shaft exploring, geophysical exploration and systematic TL dating and rock testing, a thorough investigation on the geological setting and the geological structure o f the landslide mass is represented. And the subzones are plotted out. The mec hanism of the sliding and the evolution of the Jingsha River are analyzed. The c onclusion is that the ancient landslide mass is located in the ancient river ch annel and ancient landslide is stable. This conclusion provides a strong basis t hat the hydro -power station could be constructed in the area and it also play a n important role for study the evolution of the Jinsha River. The achievements a nd the experience can be adopted for the other similar hydro -power projects that will be developed on Jinsha River.
