摘　　要：驮英水库溢洪道边坡开挖揭露岩体多为粉砂质泥岩,为较软岩~软岩。分析了溢洪道边坡变形的原因,并对其地质情况进行了评价。针对溢洪道右侧边坡处理,选取了锚索(1500 kN)+钢筋桩和锚索(1000 kN)+抗滑桩两个方案进行比选,推荐采用锚索(1000 k N+1500 kN)+钢筋桩方案。并对处理后的边坡抗滑稳定进行计算分析。At the flood spillway of Tuoying Reservoir,slope excavation reveals that the rock mass is mostly relatively soft~soft silty mudstone.The author analyzed the causes for slope deformation,and evaluated the geological situa-tion.For the treatment of flood spillway right slope,the scheme of anchorage cable(1000 kN+1500 kN)+reinforce-ment pile is recommended after two alternatives of“anchorage cable(1500 kN)+reinforcement pile”and“anchor-age cable(1000 kN)+anti-sliding pile”were compared.Anti-sliding stability calculation and analysis were con-ducted for the slope after treatment.
