摘　　要：通过十字板剪切试验、轻便触探试验、室内含水量试验、室内直剪试验等试验手段分析了某高速公路黄土边坡的植被加强作用,即植被对斜坡土体力学参数的影响,研究了两种植被区域:狗牙根和结缕草与高羊茅混播区。并定量研究了植被根系对浅边坡的影响,试验结果表明,植被对浅边坡稳定性具有潜在影响。该研究对指导工程实践具有理论和实用价值。By using vane shear test, portable sounding test, water content test and direct shear test, the strengthening effect of vegetation on the soil slope of an expressway, i. e. the influence of vegetation on mechanical parameters of slope soil is researched. The tests are done in two kinds of vegetation areas. The result indicates that the vegetation has potential influence on the stability of shallow slope. Through tests the quantitative influence of the vegetation on the shallow slope is analyzed.
