| 摘 要： | 以三峡水利工程为背景,针对长江三峡库区水位的周期性调节对库岸边坡稳定性可能产生的种种不利影响,计算了在库水位下降期间,滑坡体稳定性受库水位下降速度影响的变化情况。结合库水位下降期间不同渗透系数滑坡体的实际渗流场,对滑坡体稳定性进行了数值计算分析,得到了库区降水速度和渗透系数与边坡稳定性之间的变化规律,对库区边坡稳定性的研究有一定的参考作用。 |
| 关 键 词： | 工程地质 库水位 滑坡体 稳定性 渗透系数 |

| Abstract: | The reservoir water level in the Yangtze River Three Gorges Reservoir area is adjusted periodically,so the stability of the landslides on both banks is affected seriously.Under the background of the Three Gorges irrigation projects,the influence of drawdown speed of water level on the stability of landslide was analyzed.The variation of the landslide stability at different time during water level drawdown was analyzed considering the actual seepage fields.Through numerical calculation,the relationships of the landslide stability,the seepage coefficient and drawdown speed were obtained.It has some referential values for the study on the sliding stability of slope. |
| Keywords: | engineering geology reservoir water level landslide stability permeability coefficient |
