The Characteristics Of Soil Erosion And Prevention Measures Of Jiangxi Province Highway Development And Construction Process

Jiangxi highway project development and construction process resulted in a lot of soilerosion and caused a great deal of spoil, spoil, destroy vegetation, causing soil erosionand the destruction of the ecological environment,the urgent need for the development andconstruction projects and prevention of soil erosion be monitored. In this paper, pegs,artificial rainfall simulation method for three typical highway project in Jiangximonitoring,it briefly analysis the measures of soil and water conservation of the threehighways of the development and construction of Jiangxi province highway engineering inthe process of soil erosion characteristics and measures of soil and water conservationcharacteristics,, as follows:(1) embankment fill slope soil erosion modulus is about1.41to1.75times the cutting soil cut slope erosion modulus，(2)the entire construction process,phase characteristics significantly, cuttings cut slope, embankment fill slope, borrow pitsexcavation slope, borrow pits accumulation slope, spoil ground accumulation slope, spoilground accumulation of soil erosion dynamic change platforms, both showed an invertedU-shaped;(3) the same slope cutting the rate cut slope, embankment fill slope of soil lossand its positive correlation between the length of the ramp; under (4) the same slopelength conditions, borrow pit excavated slope, soil erosion volume of spoil groundaccumulation slope gradient and its positive correlation;(5) In different regions of Jiangxiprovince, the excavation slope, embankment fill slope of expressway account for theprincipal part of the project is different, the highway in mountainous areas of southernJiangxi> the highway in Hilly Area of central Jiangxi> the highway in plain、basin area ofnorthern Jiangxi；the extent of soil erosion in mountainous areas of southern JiangxiExpressway> extent of soil erosion in hilly area of Jiangxi Expressway> extent of soilerosion in plain、basinal areas of northern Jiangxi；（6）the place of cutting slope height≤3.0m and embankment slope height≤4.0m use plant measures，the place of cuttingslope height>3.0m and embankment slope height>4.0m use engineering measures orengineering measures and plant measures combined；（7）From the economic benefits,considering the effect of slope protection, seeding grass and shrub slope control effects>Three-dimensional network seeding grass slope> sod revetment.
