在地质测绘、钻孔与平硐勘探、物探测试、系统测年、岩土试验等大量地质勘察资料的基础上，系统阐述了金坪子滑坡的地质背景、地质分区。查明了金坪子滑坡Ⅳ区为基岩斜坡；滑坡Ⅴ区为古基岩离堆山；滑坡Ⅰ区主体堆积于一呈槽状的侵蚀缓坡上，总体稳定；滑坡Ⅱ区主体为由古冲沟堆积和崩滑构成的堆积体，呈蠕滑状态。在查明Ⅱ区地下水补径排关系的基础上，提出了地下(表)截排水作为滑坡治理的基本方案。滑坡Ⅲ区位于金沙江古河槽中且处于超稳定状态。研究成果为乌东德水电站开发方案的确定和坝址比选提供了翔实的基础资料。

On the basis of a large amount of geological data of surveying and mapping, hole-drilling and adit investigation, geophysical test, systematic dating, rock and soil test etc. , the geological background and geological zoning of Jinpingzi landslide of Wudongde Hydropower Station are systematically described. The analysis shows that the zone IV of Jinpingzi landslide is a bedrock slope, the zone V is an ancient bedrock meander core, the main body of zone I is an accumulated body on a trough-shape erosion slope and in a stable state generally, and the main body of zone II is an accumulated body formed from ancient gully accumulation and slump and in a creep state. After investigation on the water supplement, runoff and discharge of zone II, the underground ( surface) flow cutoff and discharge is determined as the basic treatment scheme for the landslide. The zone III is in the ancient Jinsha River channel and in a super-stable state. The research results provide detailed fundamental data for determi-nation of cascade development scheme and dam site comparison and selection.
