摘要
驮英水库溢洪道进水渠及渐变段右侧边坡坡脚清渣之后,在坡顶截水沟边缘及上游侧转弯处边坡上出现了多条拉裂缝,边坡发生了变形。本文分析了边坡变形产生的原因,并对该岩质边坡稳定性进行了分析计算,然后从技术、经济、施工条件等3个方面对3种处理方案进行了比选。
After slag removal at the right bank slope foot of inlet channel and transition section of the flood spillway of Tuoying Reservoir,multiple tensile cracks were found at the top cutoff ditch edge and the upstream turning section of slope.Analysis was made on the causes for this bank slope deformation.The stability of this rock slope was analyzed and calculated.Three treatment alternatives were compared in respects of technique,cost and construction conditions before selection.
