Huang Ta (Tao) Highway Rock Slope Of The Ecological Restoration Technology Research

Ecological rehabilitation and Sight design are kinds of engineering technology rising with construction of Expressway in the whole world.Ecological rehabilitation is an perfect combination of plant protecttion and protection project,which is full use of reinforcement and protecttion of deep-shallow slope and environmental protection to achieve the characteristics of the project construction and environmental protection and get the point of construction and environmental protection and ecologyical restoration.Nowdays,people pay more attention to environmental protecttion and life quality,using Ecological rehabilitation becomes a kind of trend in slope protection of highway,it also represents the developing direction of slope protection.Therefore,the issue has become a slope above ecological restoration and slope protection works worth studying the subject.At present researching mainly of Ecological rehabilitation technology concentrate on construction craft and researching on water and soil conservation,Overlook the slope of plant roots' effecting of mechanical engineering ang the combination of research between plant protection and engineering protection.Overlook the different rock Characteristics,climate,human environment,and other aspects,and comprehensively consider the selected native vegetation whether suit the growth environment or not.The rock slope is more than 90%in the slope of HuangTa(Tao)highway,stability better and bare rock slopes are mass.A majority lithology of slope is slate,sandstone and granite.Becausr of those reason,increased the slope of the ecological recovery Great difficulty.This article is based on the above reasons,relying on key roads in southern Anhui onstruction projects——HuangTa(Tao)highway landscape construction of the ecological system research project,the main research work completed as following. First of all,through access to research the status quo of domestic and overseas, and expounded completely on the slope of the ecological restoration of the mechanical effects,hydrological effects,visual effects and ecological effects of the basic theory.Then,On the basis of the first point,after the scene environmental geological survey,soil(rock)kind of nutrients and domestic highway slope restore the status quo of ecological survey,in study area,found that the slope lithology is little acid and rock nutrition Ingredients mixed,with the exception of potassium-rich, nitrogen,phosphorus and organic matter are scarce,in the substrate to be joined in the ratio of slow-release fertilizers,soil or sludge Northeast,carbon soil and so on.Thirdly, commonly used vegetation ratio test,transplanting native plants test and the scene of the thick vegetation substrate Spraying(transplant)etc.Screened for ecological restoration of the tree,shrub,grass and vegetation of the vine species number is 13,22,12,6;Identified wujiemang and guanyincao are able to transplant if cut their treetop;optimized the scene Construction Technology,vegetation and the planting of proportion.Finally,considered to the slope lithology,integrated slope stability and support building,and divided the rock slope to three broad categories:supporting structure of the rock slope,no support structure of the rock slope and the slope landscape design,and combined slope stability,plant roots and soil of rock, topography,and other practical factors,work out different effective representative of the plant configuration and construction of ecological restoration technology programmes.In addition,in view of the highway along the slope of the specific conditions of a typical rock slope ecological restoration and landscape design on the actual application,the proposed study area along the highway typical slope landscape and ecological restoration of the theory programme,at the same time,used of some kinds of Softwares to make consequential effect of the landscape plans.
