Icing problems on road in Da Hinggangling forest region and prevention measures
AbstractIcing problems on road in Da Hinggangling forest region, northwest of China, are very serious. Many measures (blind ditch, pit for containing ice, fences/dams for blocking ice, insulated drain, etc.) have been used in this cold regions but they were not always effective. This paper analyses the formation reasons of icing and the disabled reasons of the old measures and represented a set of composite measures applied to control the icing problem on road in Da Hinggangling forest region. Results show that the frosty climate and the complex hydrology conditions and the inadequate field exploration are the main reasons that led the prevention measures to be disabled. The innovation of the technique is the “double-drainage openings” insulated drainage system. Practice proved that it had good effect on control icing problem on road, and also it could protect woods resource and ecology environment.
