| 摘 要： | 为查明云阳县某斜坡体出现多种变形特征的原因，对整个斜坡变形体进行全方位勘察，并进行稳定性评价。通过工程地质测试手段以及室内测试分析方法进行研究，选取三个关键剖面进行不同工况下的稳定性评价。结果表明:该斜坡变形体在枯季工况下稳定，在暴雨工况下由西向东稳定性依次降低；库水位影响下的坡体稳定性明显降低；在斜坡体欠稳定处实施支挡工程后的剖面稳定性明显提高，且下滑力显著降低，表明支挡措施合理有效。因此，该斜坡变形体有必要进行工程治理。

Stability Evaluation of a Slope Plasmodium in Yunyang County |
| |
| Abstract: | In order to find out the reasons for the deformation characteristics of a slope body in Yunyang County, an all-round investigation was carried out for the entire slope plasmodium and its stability was evaluated. Three key sections were selected to evaluate the stability under different working conditions by means of engineering geological testing and indoor testing analysis method. The results show that the slope plasmodium is stable in dry season and its stability decreases from west to east in heavy rain. The slope stability is obviously reduced under the influence of reservoir water level. If the section stability is obviously improved and the sliding force is obviously reduced if retaining works are carried out at the slope body under stability, the retaining measures are reasonable and effective. Therefore, it is necessary to carry out engineering treatment for the slope plasmodium. |
