摘　　要：在考虑软土地基的固结和土体的非线性应力应变关系的基础上,利用有限元的数值方法对加筋路堤的受力性状和破坏机理进行了分析。分析结果表明,加筋可以减少路堤的沉降,以及侧向位移,并能增加路堤的稳定性。研究成果对软土地基的加筋处理有一定的指导意义。Considering soft ground＇s consolidation and the nonlinear constitutive relation of the soil,the behavior and destruction mechanism of reinforced embankment under loads by means of finite element method are analyzed.The results show that the reinforcement can improve the embankment stability,reduce the settlement and lateral displacement.Research achievements has some guidance for soft ground＇s geogrids reinforcement.
