丹水出口段右岸潘家堂变形体边坡稳定分析及加固治理

Stability Analysis and Reinforcement of Panjiatang Landslide Body on Right Bank of Danshui Outlet Section

研究丹水出口段潘家堂边坡变形体产生的机理,根据其地质情况,采用HH-slope软件对现状边坡变形体进行稳定分析计算,所得滑动区域与实际勘测变形体基本一致;采用对潘家堂岸坡变形体上部岸坡削坡减载和下部岸坡高压注浆的综合加固治理措施,复核计算各工况下岸坡的稳定性均满足规范要求。实践证明治理措施取得了较好的效果。

The deformation mechanism of Panjiatang landslide body on right bank of Danshui outlet section is studied. Considering the actual geological conditions, the stability of the landslide body is analyzed with HH-slope software. The calculated sliding zone is basically consistent with the survey results. Then, comprehensive reinforcement measures with the upper slope cutting and load reduction and the high pressure grouting in lower bank slope are adopted. Stability calculation results of the slope under different working conditions show that the specification requirements are satisfied. Practice shows that the treatment is satisfactory.
