摘要

以纳坝水库溢洪道左岸古滑坡为研究对象，对滑坡工程地质条件进行了评价，分析了古滑坡体复活前变形特征及复活的成因机理，结合滑坡体实际情况和同类工程经验进行了综合处理方案研究，并有效治理了滑坡体。经监测，滑坡体处于稳定状态，保障了溢洪道泄洪安全。

Abstract

This paper

taking the ancient landslide on the left bank of spillway of Naba reservoir as the research object

evaluates the engineering geological conditions of landslide

as well as analyzes the de_ formation characteristics of ancient landslide before reactivation and its reactivation mechanism. The comprehensive treatment scheme of landslide is studied in combination with the actual situation of land_ slide and the experience of similar projects. After comprehensive treatment

the landslide body is effec_ tively remediated and in a stable state

ensuring the safety of the flood discharge through the spillway.
