The Ecological Slope Protection Study Of Shaanxi Expressway

With the rapid development of the Shaanxi expressway, environmental issues havebecome increasingly prominent, slope protection problem has also been increasing attention.Slope protection methods, from early single engineering protection gradually shift toecological protection. An ecological slope protection can greatly reduce the cost of slopeprotection, it also can through mix different plant species, to create different visual effects.But different ecological slope protection scheme has its applicable conditions and scope,and the state had no corresponding standard to guide the design and construction, roadengineering staff, often only by experience or copy other areas slope protection technology.Coupled with the design staff are lacking of study on growth characteristics and effects onplants, as well as separate design engineering protection and vegetation planted usually,increasing the initial investment, and maintenance costs, more serious will quickly so as tocause more serious disasters such as slope collapse because of slope vegetationdegeneration.In this paper, based on the ecological slope protection on basic theoretical research,detailed investigation on the status of Shaanxi highway ecological slope protection, on theone hand,an analysis of Shaanxi Expressway common ecological slope protectiontechnology, and then classify the slope, according to certain principles, through objectivecomparative analysis provides the best protection technology in different slope conditions;on the other hand, analysis of suitable planting vegetation and common plant configurationof the area, then according to the protection effect and growth of different various plantconfiguration, Through an objective comparative analysis, proposed the optimal plantconfiguration of different regions. Finally based on the study of determining principle ofthe preferred embodiment of ecological slope protection, According to the determineprinciples,proposed the optimal ecological protection programs of Shaanxi Expressway.This provides a better reference for designers, construction personnel, save the cost, at thesame time, the ecology has positive significance to the construction of "beautiful China",also lay a certain foundation for the national relevant regulations and technical standards ofecological slope protection...
