摘　　要：本文针对某拟建软基上加筋土挡墙工程,对地基处理时采用的不同方法进行了平面有限元分析。通过计算比较它们对路堤底面应力分布、侧向位移、垂向沉降的影响,阐述了土工格栅加筋垫层作用和效果。This paper makes a finite-element analysis of the treatment of the soft foundation under a building reinforced-soil segmental retaining wall. By comparing the relations among vertically distributed stresses, horizontal displacement, sedimentation on the surface of the roadbed and several foundation treatment methods with the calculated results, the paper explains the effects of the grids on the bedding cushion.
