一、前言本文对修建在适用的地基上坡边为1:1的无加筋路堤和聚合物加筋路堤进行了非线性有限元分析。对两者作了分析对比,以考察土边坡内聚合物加筋的影响。结果表明:由于采用了加筋,边坡内的剪应变、水平应变及竖向应变都明显减小。加筋路堤结构的有限元分析得出了加筋内荷载的大小及分布。对于所有路堤高度,加筋所受的最大荷载不出现在加筋的最底层而是出现于铺设在地基之上0.4H处的加筋层中,这
I. INTRODUCTION In this paper, non-linear finite element analysis of non-stiffened embankment and polymer-reinforced embankment with a 1:1 slope on the applicable foundation is performed. Both were analyzed and compared to examine the effects of polymer reinforcement in the soil slope. The results show that the shear strain, horizontal strain and vertical strain in the slope are significantly reduced due to the use of reinforcement. The finite element analysis of the reinforced embankment structure gives the size and distribution of the reinforced internal load. For all embankment heights, the maximum load imposed on the reinforcement does not appear at the bottom of the reinforcement but appears in the reinforcement layer at 0.4H above the foundation.
