| 摘 要： | 为探索根系与土体间相互作用的特性,基于库仑理论,采用直接剪切的方法,对油松根系和刺槐根系与黄土在不同含水量、土壤密度条件下进行不同法向荷载作用下的剪切试验,得出了油松根系和刺槐根系与黄土之间的剪切特性,刺槐根系与黄土间的摩擦阻力大于油松,并讨论了法向应力、树木根系种类、土壤密度及含水量对接触界面剪切特性的影响。

| Abstract: | In order to probe into the frictional characteristic between root system and soil,based on the Coulomb theory,under different soil water content and soil bulk density,different normal load between root system of Pinus tabuleeformis,Robinnia pseudoscacia and soil,the shear characteristics between root system of Pinus tabuleeformis,Robinnia pseudoscacia and soil were investigated by the method of shear tests.The results showed that the frictional resistance of between root system of Robinnia pseudoscacia and soil was higher than that of Pinus tabuleeformi.At last,the influences of normal stress,root system species, soil bulk density and soil water content on the shear characteristic of interface were discussed. |
