Abstract

In order to investigate the effects of root content and normal stress of arbor root system on the shear strength of root-soil composite, numerical simulations were carried out for four normal stresses and five root contents of root-soil composite specimens by using the finite element numerical simulation method, and the effects of different normal stresses and root contents on the shear strength were revealed.It was shown that: the shear strength of the root-soil composite increased with the increase of root content and normal stress, respectively; the contribution of the root system to the shear strength of the soil was mainly in cohesion.The increase of normal stress weakened the strengthening effect of root system on soil; the effect of root content on shear strength was more sensitive compared to normal stress.The research results can provide a certain theoretical basis for the arbor root system to consolidate the slope and provide technical support for the subsequent development of practical engineering treatment.
