Based on the domestic and foreign scholars’research achievements on both direct shear tests and triaxial tests of plant roots-reinforced soil,this paper discussed the enhancement effect of different kinds of plant roots such as herbs、shrubs and trees on soil shear strength through direct shear tests and triaxial tests that were conducted on both undisturbed root-soil composite systems and remolded root-soil composite system,and the roots distribution of each plant in soil was different. This paper summarized the deep anchorage,shallow reinforcement of soil and oblique pulling effect of plant roots,different interaction mechanisms of the three root-soil composite systems,and the results of numerical simulation of plant rein-forced soil.
