摘　　要：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 features of the special climate,the geological conditions and the active geological structures in Qinghai province,a number of highways are located in high altitude,steep canyons and alpine regions,and various types of slope diseases occur along the highways.Based on the characteristics and causes of the slopes and on the geological survey practice about the slope diseases in the regions,five kinds of slope diseases such as loess landslide,saturated-slope disease,steep embankment disease,canyons-slope disease and red beds-slope disease are put forward,and the formation mechanism of each type of slope disease is analyzed.
