Effect of Geogrid on Deformation of Subgrade in Layered Filling for Widening
摘要
Abstract
Taking a project of provincial road widening in Sichuan as an example,the paper herein combined with numerical simulation test and field data,and studied the deformation of subgrade in layered filling for widening and the treatment effect of geogrid.The result of FLAC3D numerical simulation shows that the foundation dominates the vertical deformation of subgrade top,and the new subgrade dominates the horizontal displacement of widened subgrade top.The treatment effect of geogrid is obvious,and after reinforcement,the horizontal displacement of subgrade and foundation reduces greatly,thus the road deformation is more reconciled.关键词
