摘要
道路冻深的确定是季节冻土区路基防冻设计的主要内容之一。根据长余高速公路典型路段道路冻深的现场观测资料 ,对确定道路冻深的各种现场方法的优缺点进行了对比 ,并且对影响道路冻深大小的气温、地下水位、土质和含水量。
The determination of road freezing depth is one of the principal contents of frost prevention design about subgrade in seasonally frozen ground region. Based on in-situ observation data of freezing depth from typical road segments in Changyu freeway,this paper compares advantages and defects of various in-situ observation methods determining road freezing depth,and also analyzes those factors which influence road freezing depth such as air temperature,groundwater level,soil property,moisture content,sectional form of subgrade and route trend and so on.
