| 摘 要： | 湘西里耶防洪工程新开河道左岸边坡因连续降雨而发生蠕滑变形，并可能产生大滑坡。在对滑坡失稳机制进行分析的基础上，针对可能滑坡的地段利用最小二乘法进行了滑带岩土力学参数的反演和边坡稳定分析，最后采用预应力锚索与锚杆相结合的方案进行综合整治。监测结果表明，该治理方案是可靠的。

| Abstract: | Due to the continual rainfall,creep deformation occurred slope on the left bank of the river excavated in the flood control projects in Liye west of Hunan,and a serious landslide was likely to occur.Based on the analysis of the mechanism of landslide and slope stability,and the stratum layer parameter conversion carried on with the Least Square method,pre-stressed cables and anchor rods were used in the treatment to the slope.The monitoring result indicates that this treatment is reliable and safe. |
