| 摘 要： | 贵州省三穗至黎平高速公路K109+300~+860段右侧路堑边坡在施工开挖至最下一级边坡时,由于雨水下渗,坡体出现局部坍塌。在卸载清方过程中,边坡多次发生垮塌。随着连续降雨,坡体内地下水排出不及时,继而形成牵引式滑坡。根据该滑坡特点采用分区、分段的综合处治方案,即"抗滑挡墙(墙后干砌片石)+纵向渗沟+环向截水沟及渗沟的综合处治方案",取得了良好的处治效果。

Analysis on Genesis of Landslide in K109 Section of Sansui-Liping Highway and the Treatment Measures |
| |
| Abstract: | When excavating to the lowest level of cutting slope at the right side of K109+ 300 ~ +860 section of Sansui-Liping Highway in Guizhou Province, local collapse arose thereon because of rainwater infiltration, so the slope collapsed many times in unloading and clearing. As rain falls continuously, the ground water inside the slope can not be drained in time, leading to retrogressive landslide. Based on the slope’s features, the comprehensive control scheme in areas and sections, i.e. anti-slide retaining wall (dry masonry of rubble behind the wall) + longitudinal blind drain + circumferential intercepting drain and blind drain, got good performance in the treatment. |
