摘要： 高速公路运营多年后会存在大量边坡病害问题，严重影响着高速公路的运营安全。选取浙江某运营高速公路K36+220～K36+485处的不稳定边坡，从地形地貌、地层岩性、地质构造及地震、气象水文与水文地质条件等方面查明了边坡所在的区域环境。通过野外调查查明了边坡的形态特征及病害特征，对边坡稳定性进行了定性和定量评价，并提出了治理建议。

Abstract: Significant amount of safety hazards are accumulated on the highway slopes after years of opening to the traffic and these hazards impose a potential threat to the safety of highway operation. The paper presents the case study of the instability concerns of the live trafficked highway segment between K36+220 and K36+480 in Zhejiang Province. The regional factors, such as, topography, subsurface lithology, tectonic structures, seismic conditions, meteorology and hydrology conditions, are investigated. The characteristics of the highway slopes and their associated hazards are presented. Both qualitative and quantitative evaluations of these highway slopes are performed and mitigation recommendations are proposed.
