摘　　要：高速公路建设期,为保障施工过程中边坡安全,应对边坡开挖与支护开展监测监控工作,实现边坡的动态反馈指导设计与信息化施工,但在运营期病害高边坡的应急处治中运用较少。鄂西恩黔高速咸丰互通路堑高边坡地质条件复杂,在建设期、试运营期出现不同规模的边坡平台垮塌、挡墙开裂及中央分隔带偏移等病害,处治难度大,施工风险高。通过对该边坡的应急施工前期、应急施工期及施工运营等阶段的安全监控,为高速公路处治方案的决策、施工期的运营安全及施工动态反馈提供了监测数据和监控依据,保证了该病害边坡的施工处治顺利进行,并为处治效果评价提供了依据。工程案例提出的病害边坡应急监控期、施工处治期及施工完成后运营期等3阶段安全监控模式为其他高速公路运营期病害边坡处治的安全监控工作提供了一个标准样本。The geological conditions of a high cutting slope located in Xianfeng interchange of En-Qian Expressway are very poor.During the construction period and the trial operation period,the slope platform collapse with various scale,retaining structure cracking and median separation zone deviation are observed which makes the remediation difficult and with potential high risk.Throughout the safety monitoring of the slope in the early stage of the remediation,the emergency remediation period and the operation period,the monitoring data are provided for the expressway operation safety and construction real-time feedback,which ensures the smooth construction treatment of the slope hazards and provides the basis for the remediation effect evaluation.
