Experimental Study of Influenial Factors of Slope Protection Through Grass Jetting on 3D Geomat

  • 摘要: 采用室外边坡模型正交试验方法,综合比较分析了土工网垫类型、草籽播种密度、边坡土质、边坡坡度等4个因素对坡面的最终侵蚀模量、浅层土抗剪强度和平均渗透系数3个试验指标的影响显著性,并给出了各因素对试验指标的敏感性顺序,进而应用综合加权评分法得出护坡效果最好的试验组合.分析结果显示,坡度为1∶1.5、网垫型号为EM4、土质为粉质黏土、草籽喷洒密度为预设最大密度时,边坡侵蚀模量最小、坡面浅层土抗剪强度和渗透系数最佳.
    Abstract: Based on ecological slope protection models through orthogonal tests,the comparative analysis of effects of slope protection is conducted by considering the types of geomat,density of grass seeds,types of soil,and slope gradient on erosion modulus.Shear strength of surface slope soil,permeability coefficient,and the sequencing sensibilities of influential factors are presented.Furthermore,the optimum combination considering various factors is obtained with a general weighted scoring method.Results show that the optimum effect for general consideration on erosion modulus,soil shear strength,and permeability coefficient can be achieved when using the slope gradient of 1∶ 1.5,EM4 3D geomat,silty clay,and the maximum density of grass seeds.
