植被护坡是目前边坡防护中常用的一种方法。针对植被护坡中常用的草本植物，文章分析了其护坡固土机理，对其根系固土效果进行了研究。通过室内直接剪切试验，测出含有不同量的狗牙根根系和麦冬草根系的根土复合体的抗剪强度，分析了根系质量分数对土体抗剪强度的影响，得出根土复合体的锚固效应强度公式。试验结果表明，根系的存在可以明显提高土体的抗剪强度，而且根系质量分数越大其效果越好。

Ecological slope protection is a commonly used method in slope protection at present .For commonly used herbs ,the mechanism of slope reinforcement was analyzed and the effect of roots on slope reinforcement was studied .Through laboratory shear tests ,the shear strength of the root and soil composite which contains different amounts of bermudagrass roots and ophiopogon roots was got-ten ,the impact of the root content on the shear strength of the soil was analyzed ,and the anchoring effect strength formula of the root and soil composite was obtained .The results show that the pres-ence of roots can significantly improve the shear strength of the soil ,and the greater amount of roots , the better results .
