| 摘 要： | 水库区水位的调节及降雨作用对滑坡稳定性的影响过程是动态变化的。以三峡库区紫阳城滑坡为例,采用地下水浸润线简化求解公式,对滑坡的动态稳定性进行了分析,并与目前的常规评价方法进行了对比。结果显示,库水位上升时,常规分析方法评价结果是稳定性偏高;而库水位下降时,评价结果反而偏低。因此,采用动态评价方法比较符合实际;并据此对该滑坡防治工程进行了优化分析评价。 |
| 关 键 词： | 库水升降 降雨 地下水浸润线 滑坡动态评价 防治工程优化 |

| Abstract: | In the reservoir basin,the regulation of the reservoir water line and rainfall action will lead to the fluctuation of the groundwater level of a landslide.This will have influence on the landslide stability.Because this course is dynamic variable,the stability is lowest and the evaluation result is not consistent with that by the static evaluation method.Based on this,taking the Ziyangcheng landslide in reservoir area of the Three Gorges as an example,this paper uses the simplified formula of groundwater sa... |
| Keywords: | reservoir water level fluctuation rainfall groundwater saturation line landslide dynamic evaluation optimization of prevention project |
