摘要

水库库岸失稳是水利水电工程中常见的边坡变形方式。由于水库蓄水

水位上涨

引起地下水位升高

岩土体内的断层、裂隙和空隙中的水压力发生变化

使岩土体的强度指标弱化

将可能引起古滑坡体复活或促成新的不稳定滑体。初步探讨了对西北地区中小型水库的库岸稳定机理

通过研究分析

提出了库岸稳定预测的计算方法。

Abstract

Landslide and collapse are two basic types of bank destruction occurring in medium and small-sized reservoirs in the northwestern region.Based on numerous site investigation，the relationship between the bank stability and the characteristics of medium and small reservoirs is studied，and the destabilising mechanism of reservoir banks is analysed.Calculation methods for several types of evaluation of loess bank slope stability are proposed.It is shown that the results of the calculations agree with reality.
