摘要
赵树岭滑坡是三峡工程库区的重要滑坡 ,其稳定性直接关系到巴东新县城沿江大道的安全 ,并对新县城土地利用意义重大 .在阐述赵树岭滑坡基本特征的基础上 ,运用水岩耦合三维有限元数值方法模拟了滑坡稳定性 ,预测了三峡水库蓄水后滑坡稳定性发展趋势和渗流特征 .研究表明 ,水库蓄水及水位波动是影响滑坡稳定性的主要因素 ,三峡水库蓄水后 ,滑坡将发生局部失稳 ,必须加以治理 .
The safety of the Zhaoshuling landslide, one of the most important landslides in the Three Gorges Reservoir, is directly related to that of Yanjiang Road which is located along the Changjiang River, and is also important to the land use of the Badong County, a new established county. This paper first describes the essential features of the Zhaoshuling landslide, and then presents the simulation of landslide stability using 3D finite element method for water stress coupling, and the forecasting of the landslide stability trend and permeability features after the Three Gorges Reservoir is in operation. The research shows that the change in the reservoir water is the major factor to affect the stability of the landslide. After the Three Gorges Reservoir is in operation, some parts of the landslide will turn instable. In this sense, this paper offers some principles and counter measures to prevent and treat the landslide.
