摘要

基于位移监测、数值计算、室内和现场试验等成果，从动力学角度开展了李家峡坝前水库滑坡稳定性预测的系统研究，获得了其滑带土的蠕变特性及水库滑坡的蠕滑机制，提出滑面剪应力比和滑带土黏滞系数的增减是决定滑坡能否从蠕滑转入剧滑的内在条件；通过模拟水库运行环境，完成了代表性滑块的现场促滑试验，研究表明：该类试验既是论证滑坡蠕滑机制的可靠方法，也是水库滑坡增稳治理的有效手段之一。

Abstract

According to the landslide dynamics

a systematic study on the stability prediction of reservoir landslide of Lijiaxia Hydropower Station is conducted based on the results of in situ monitoring

numerical analysis

laboratory and in-situ tests. The creep characteristics of the soil in the sliding zone and the creep-sliding mechanism of the reservoir landslide are obtained. It is shown that the varieties of both the shear stress ratio on the sliding plane and the viscosity coefficient of the soil in the sliding zone play an important role in transforming the landslide behavior from creep sliding to sudden sliding. Moreover

a typical sliding block of the landslide is chosen to carry out in-situ sliding test; the test is implemented under the simulated environment of reservoir; and the variation of the reservoir water level is taken into account. The study shows that in situ sliding tests can be not only a rational approach of verifying creep-sliding mechanism of reservoir landslide but also an effective measure to enhance the stability of landslide.
