青海省多条公路处于高海拔、高陡峡谷及严寒地区,由于受特殊的气候和地形条件、复杂的地层岩性以及活跃的新构造运动的影响,使得公路沿线产生较多的不同类型的边坡病害。笔者依据多条公路沿线边坡病害的地质勘察实践,按照公路边坡病害的特点及产生的成因,将青海地区公路沿线边坡病害归纳划分为黄土滑坡、高含水边坡、陡坡路堤、峡谷区边坡和红层边坡病害等五种类型,并对每种类型的边坡病害的形成机理进行了分析。 Due to the special climate and topography, complex stratigraphic lithology and active neotectonic movement, many highways in Qinghai Province are in high altitude, steep valleys and cold regions, resulting in many different types of edges along the road Slope disease. According to the practice of geological survey of slope diseases along several highways, according to the characteristics of highway roadside diseases and their causes, the authors classified the roadside diseases along the highway in Qinghai Province into loess landslide, high water cut slope, steep slope embankment, gorge area Slope and red bed slope disease five kinds of types, and each type of slope disease formation mechanism was analyzed.
