The Ecological Protection of Slope Surface in Highways at High and Cold Mountainous Regions in Southwest of China

This research takes the reference on the advantages and disadvantages of highway slope surface protection methods, this paper proposes a combined ecological protection measure of plant protection and engineering protection and considers it as the future of highway slope surface protection. Since Duilongdeqing County, Lhasa lies in a typical high and cold mountainous region, this pager take Binhe Road and Donghuan Road projects to be the case studies to highway slope surface in high and cold mountainous regions through the analysis of the local meteorological, hydrological and geological conditions.
