| Abstract: | With vetiver grass roots as the research object,root and the soil as a whole.The change of shear strength indexes of root-soil composite with the quantity of grassroots plantees in the soil samples was investigated.Laboratory triaxial tests were carried out in order to understand the stress-strain relationship and strength property of root-soil composite.The strength property and the failure modes of soil and root-soil composite were contrasted. |

| Keywords: | root-soil composite soil triaxial tests stress-strain strength |
