摘要

针对目前较少研究香根草在边坡防护的力学作用的情况

通过香根草力学试验

测定、分析香根草的力学指标

定量检验香根草在边坡防护中的力学作用。通过试验分析发现

香根草护坡可以提高土的黏聚力和内摩擦角

从而提高土的抗剪强度

进而增加土壤稳定性。香根草根系必须达到一定密度

抗剪强度才能提高

从而发挥边坡防护的作用。

Abstract

In view of a few mechanics researches on vetiver grass applied in railway side slope protection

mechanics functions of vetiver grass were investigated through a test for vetiver grass and an analysis of the mechanics index. Vetiver grass is found to increase adhesion and internal f riction angle

enhance shear st rength and improve soil sta-bility. The test shows that only if the density of vetiver root system reaches to a certain value

shear st rength can be enhanced significantly

which implies a great role of vetiver grass in railway side slope protection.
