梅列互通滑坡的历时变形分析及治理效果评价

Studies on the Deformation Mechanism of High Slope and Assessment of the Treating Effect by Monitoring

为复杂高边坡滑坡病害的预防与治理提供借鉴与指导作用,基于坡体变形测斜实测数据,并结合地质钻孔资料与坡面逐级开挖观测资料,对梅列互通高边坡滑坡病害的发生与发展规律与预防措施进行了分析研究。结果表明:施工开挖对坡体稳定度的影响规律同坡体的宏观历时变形破坏表征具有一致性;从坡体测斜位移监测曲线来看,应急锚固和根治锚固工程都有效地抑制或减小了加固坡体范围内的变形,应急锚固在抑制坡体变形的同时影响或增大了坡体深部的变形;根治锚固工程首先抑制住坡体深部变形的发展,继而使坡体的浅部变形趋向停止。综合分析各工况阶段的监测结果表明,梅列互通边坡滑坡经治理后,坡体已趋于稳定状态。

Based on the inclination survey data and the drilling and excavation revealed the slope, the deformation law of cut slope of the Meilie interchange landslide disease have been studied. The results show that influences for slope stability by the excavation consistency with on-site excavation of the slope deformation and failure characteristics. The slope displacement monitoring revealed, the emergency and radical anchor engineering effectively reduced the slope deformation, but it increased the deformation in the deep part of the slope. As a result, the comprehensive analysis of the monitoring results, the Meilie landslide has stabilized. Research results may prove the prevention and treatment of other typical landslide disease.
