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。 Many years after the operation of the highway there will be a large number of slope disease problems, seriously affecting the operational safety of the highway. Select the unstable slope of K36 + 220 ~ K36 + 485 in a certain expressway in Zhejiang Province, and find out the regional environment of the slope from aspects of topography, formation lithology, geological structure and earthquake, meteorological hydrology and hydrogeological conditions . Through the field investigation, the morphological characteristics and disease characteristics of the slope were identified, and the stability and stability of the slope were evaluated qualitatively and quantitatively.
