Research Of Highway's Landscape In Mountain Area

Recently,the people have being increased requirements for highway quality,not only have the safety, convenience and comfortability,but also emphasize environmental protection, beautifies , humanity. As a result, the researchers have begun to impose on Highway Landscape and gotten some active outcomes. But compared with developed country , there is very great disparity. So, this text deepens to this new subject of landscape design of the highway but systematic research, under guaranteeing the prerequisite that such functions of use as highway safety , fast , comfortable , economy ,etc,realize highway and coordination of the view are unifiedThis text has explained the development of the view of domestic and international highway, study superhighway landscape theory,set up the design principle of slope ,intercharge district and etc, analysed in depth and summarized the nine superhighways to build successful spots of Chuan Jiu's road,Xi Han's road and Si Xiao's road.Totally explained view platform set up, select site principle basically , put forward view platform divide into second concept especially,and carry on view platform planar design to someroad.Through compared and analysed the central authorities separate bringing; in the middle of the domestic and international highway, pointed out that plants to defend are all tall,so can't control the vertical slope and general situation of driving a vehicle glare at night of vertical curve place effectively. Propose four respects carry on plants and defend dizzy research from hiding all horn , defending dizzy width and interval , defending dizzy height, analysed the characteristic of the vertical curve of concave shape of highway especially, put up the height of the plant will vary with vertical curve, the minimum plant highly regards 1.8m as the centre to make and swing slightly, reaching can control more than 90% of the glare effectively , dispel the potential safety hazard that the glare brings at night basically.The text renly on"Jiang Yan highway"in JiLin province and"Zhang Shi highway"in He Bei province, combine humane characteristics ,the land view of the way , environmental one's own characteristic in the areas of Baoding , Jilin, research and propose thoroughly slope protect, the central authorities separate bringing, view platform subjections and so on, divide the characteristic view of the expressway to take. And apply to practise in project the theory achievement , obtain a lot of valuable practical experience.
