摘　　要：为了定量化分析扦插措施根系对边坡稳定性的贡献,采用固结不排水三轴剪切试验研究不含根土体及根-土复合体的抗剪强度,并使用数显土壤紧实度仪对边坡的紧实度进行测量,分析新生根系对边坡紧实度的影响。结果表明:加根土的强度和抗变形能力增强。扦插措施新生根系能有效提高土体的黏聚力,其对内摩擦角的影响不明显,而对边坡土壤紧实度的改善作用显著。In order to make a quantitative analysis of the contribution of root system by cutting measures on the slope stability,consolidated and undrained triaxial compression test was conducted to study the shear strength of soil without roots and root-soil complex.The compactness of the slope was measured by using digital soil compactness meter.And the influences of new root system on the compactness of slope were analyzed.The results showed that the strength and deformation resistance of soil with roots were enhanced.New root system by cutting measures could effectively improve the cohesion of soil,and had no obvious influence on the internal friction angle.New root system by cutting measures had a significant improvement effect on the soil compactness of slope.
