Application Of Thick-Layer Matrid Spray-Adsorption And Linked Network Of Spraying Methords In Expressway Slope Ecological Protecction

With the development of economy and the progress of society, the transportinfrastructure created travel convenience for human beings, at the same time it destroy theoriginal surface and topography inevitably, the current conditions of road construction arealmost in the construction of complex areas, the phenomenon of excavation undermine oforiginal vegetation and soil erosion and damagement of environmental became common. Tostudy the mountain road safety and environmental protection and landscape design hasbecome the next major issue of the sustainable development of the road.Take the protection of the through cut of the BeiJing to ShangHai freeway and the matrixspray-aclsorption method as the research object to achieve the best results and reduce theproject construction cost for the center, based on variety of plants defending types and theactual situation of slope construction ,by studying on the applicability of different means ofvegetation protection to slope the for to determine the best means of effective protection ofplants defending, and achieve good results of slope protection; based on the different soiltypes, slope height, slope and the the characteristics of the surrounding landscape in thecontract range, design and then make an optimization to the matrix spray-aclsorption method.Make protection of the slope by the construction of laying of linked network of metal andnon-metal, observed the attached case of the mixed substrate, and make a study on theFeasibility of construction of laying of linked network of non-metal so as to achieve thepurpose of reducing the project cost; Make a comparative study on the thickness of sprayed ofthe base mixture material and conclude from the experience of the level of constructiontechnology and choose the best spray thickness for different kinds of slope; by changing theamount of the added material and making an analysis and comparison of construction results,and get a further understanding of the basic characteristics of various of materials and the accumulation of empirical data, so as to summarized the addition standards of a variety ofslope.By using the natural scientific methods and maximize the scale of ecological protectionmeasures in the way of slope protection, and increase the ecological content of highway, so asto explore an ecological and environmental and economical construction mode, which is moresuitable for the north mountainous area.
