摘要：GDS triaxial test system was conducted to investigate the stress-strain relationship, strength characteristic and failure mechanism of Bermuda grass root-soil complex, and the effect of different root system distribution on strength of root-soil complex was also studied. The results indicate: ①the root system can improve the shear strength of soil and limit the deformation of that complex effectively. ②The contribution of the root system to the strength promotion of the root-soil complex is mainly reflected in the increase of cohesion. ③The strength increase of the root soil complex is related to the arrangement of roots in the soil. The effects are listed in the sequence as mixed placement> intersectant placement> vertical placement >horizontal placement >inclined placement. The research results provide theoretical support for the formation mechanism of the shear strength of the root-soil complex, which is meaningful to guide the selection of slope protection plants.
