摘要
针对公路滑坡支挡结构发生变形,尚未完全破坏的情况下,结合滑坡支挡结构的变形特点,提出了考虑其残存抗滑力的滑带土抗剪强度参数反分析方法。当采用单一剖面反算时,宜通过滑带土抗剪强度参数敏感性分析,确定反算指标控制值。通过工程实例验证该方法,为滑坡治理提供了可靠依据,可供同类型公路滑坡再治理参考。
In view of the situation that retaining structure for highway landslide deforms but not fails completely, this paper, combining with the features in the deformation, proposed a back analysis method for shear strength parameter of sliding soil with the consideration of residual sliding resistance. When back calculation on single section was used, it was better to define the control value of the back calculation indices through sensitivity analysis of the sliding soil＇s shear strength parameter. The method was verified by engineering cases and provided reliable basis for landslide control, which may be taken as the reference in retreatment of similar highway landslide.
