Abstract

Abstract

Aiming at an actual substation engineering slope treatment, the model tests of the filled slope treated by different geotechnical reinforcement methods were conducted to investigate the vertical settlement and lateral displacement of the slope, and compare the deformation characteristics and stability with the plain slope, ordinary reinforcement slope and wrapped reinforcemant slope by geothextilo.On the basis, the finite element analysis was carried out, and it was found that the reinforcement effect was improved with the increase of loading. Both ordinary reinforcement and wrapped reinforcement could effectively reduce the lateral displacement and the vertical settlement. Reinforcement formed a partition effect on the plastic zone in the slope, and thus improved the stability of slope. The ultimate bearing capacity of the ordinary and wrapped reinforcement was 1.7 and 1.9 times larger than that without reinforcement, respectively, the ultimate bearing capacity of the wrapped was 1.12 times of that the with ordinary.
