W-OH材料对赣南山区土壤减渗抗蚀作用的影响
摘要
Abstract
Ganzhou City is a subtropical monsoon area with concentrated precipitation and abundant rainfall,mainly in mountains and hills,and the soil type is red soil developed by granite weathering.The content of sand is extremely high,and unfavorable natural and geographical conditions are easy to cause hydraulic erosion.The new hydrophilic polyurethane material(W-OH)can increase the adhesion between soil particles and effectively inhibit the occurrence of soil erosion.For this reason,through soil infiltration test and soil erodibility model calculation,the effects of different concentrations of W-OH solution(2.0%,3.0%,and 4.0%)on soil seepage reduction and anti-erosion of mountain slope in southern Jiangxi were studied.The results show that W-OH material can significantly reduce the soil saturated hydraulic conductivity of slope soil in Gannan mountain area,and the seepage reduction effect increases with the increase of W-OH concentration;W-OH material significantly changes the erosion process of surface soil and significantly enhances the anti-erosion ability of slope soil,among which the application of 3.0%concentration W-OH solution has the most obvious anti-erodibility effect on the soil in the experimental area.关键词
