摘要

研究下红岩堆积体的稳定性对拟建水电站大坝和附属水力设施的布置和安全有着重要的意义。本文在深入分析该堆积体基本特征的基础上

以地形地貌、变形破坏迹象及物质组成特征的差异性为依据

对其进行了工程地质分区;在此基础上

对该堆积体成因及今后变形机理进行了论述

重点分析影响堆积体稳定性的诱发因素;最后采用极限平衡法计算了堆积体整体（分区）以及局部稳定性。计算结果为分析目前堆积体的稳定状况及预测其可能造成的工程危害性提供了评价基础。

Abstract

The stability of Xiahongyan accumulation is of great significance to the proposed dam and ancillary facilities of the waterpower.In this paper

according to topography signs of deformation and characteristics of the different components

we have identified different engineering geology zones on the basis of in-depth analysis of the basic characteristics of accumulation.On the basis of this

we discussed the causes of the talus slope and deformation mechanism of the future

mainly focusing on the trigger factors which impact on the stability of the talus slope.Finally

we evaluated the local stability as well as the whole accumulation（subarea） by using the limit equilibrium method.Based on the calculated results

we could analysis the stability of the current talus slope and predict the consequences of the engineering harm caused by the instability of the talus slope.
