| Abstract: | In order to study the application technology of reinforcement properties with geocells and geogrids for highway-widening engineering,this paper used the finite difference package FLAC3D(Fast Lagrangian Analysis of Continua in 3D)to simulate and study the influence of the differential settlement rule of the subgrade,different depth of geogrids or geocell reinforcement on the settlement and stress distribution of the subgrade,based on Mohr-Coulomb model.The mechanism of reinforcement properties with Geocells and Geogrids was analyzed,and geogrid-geocell combination method was put forward to provide references for engineering design and construction. |
