内蒙古地区公路边坡防护技术

Protection Technique of Highway Slope in Inner Mongolia

内蒙古自治区公路边坡病害类型主要有冲蚀水毁、风蚀、沙埋、冻胀、融沉及盐胀、溶蚀等。针对这些病害,内蒙公路建设部门采取了因地制宜、环境协调的防护措施,主要有急流槽集中排水、整片植物防护、圬工骨架植物防护、网格植物防护、圬工防护及合理养护和禁牧等措施。经过多年实践,取得了明显的防护效果和经济效益,值得在同类地区推广。

There are many kinds of special soils in inner Mongolia,such as frozen soil,saline soil,gobi,desert,loess and weathered rock.According to field investigation,highway slope destructions include water scour,wind erosion,sand covering,freezing expansion and thaw settlement,salt crystallized swelling and soluble erosion et al.With the development of highway in Inner Mongolia,some slope protection techniques controlling these special problems are tested and practiced to protect the local environment,such as rapid flow trough drainage,distributional plant protection,plant protection with concrete framework,plant framework protection,concrete protection with suitable maintaining and herd forbidding.In years of application,it has produced significant effect and benefit and should be essential to develop on similar areas.
