The Construction Technology Research Of Hunan Highway Slope Greening

The slope greening building of highway become more and more important, and it is significance for ecological restoration and maintaining the ecological balance by green technology.By relevanting literature, studying the theory, field investigation, an-d analysis of specific example, the Green technology of ChangZhu highway is studied.The existing slope greening process optimization and technological innovateo n are explored for technical reserves and technical Reference of Hunan province exp-ressway side slope construction. The main contents are as follows:(1)The Author Investigation and Analysis ChangZhu highway of Climatic conditions, road domain conditions, topography,engineering geological onditions and plant resources, slope overview. and know some features about ChangZhu highway: Complex terrain, the part slope are high and steep; native vegetation is more thorough destruction; The profile the soil is thin, weathered layer and rock layer is thickness, and slope geological structure is not conducive to plant growth; Distinct wet and dry climate all year round, severe rainy season rain erosion on the slope;Plant species are the rich along and can be used.(2)The author summarizes the characteristics of each of the slope greening process, and analysis of the technical difficulties of ChangZhu highway about slope greening protection. It can be knew that Thick layer substrate technology, vegetat-ionBag can be used in the slope of ChangZhu highway, but both processes should be based on the actual situation of the slope to improve and optimize appropriate.(3) Matrix proportion of slope greening process, plant design and the use of optimization were explored, and it provide theoretical and technical support for the highway slope greening process improvement optimization basis.(4)Greening process optimization. According to the actual situation of the long Expressway,it main Planted mainly in the matrix, a variety of green technology combinedwith the useof greenplants growing designoptimization, andit haveachieved goodresults.By the the Greening processofoptimization,itincrease theslope of Plant Pr otection,strengthen thestrength of the substrate itself, and reduce costs, reduce the construction difficulty, to a certain extent to solve the problem of rock slope greening, increased greening form,strivetoachieve the long-term effect.With the rapid development of the socio-economic, there is a higher level of requirements about people living environment. Highway slope greening has also become an important part of the landscape design. The slope greening is significance for slope protection, ecological restoration, Landscape Construction, and create a high degree of unity of Society and economic, and get real ecological environment.
