| 摘 要： | 在文献1]的基础上,考虑了柔性桩承式加筋路堤中加筋体上下摩阻力,然后对柔性桩承式加筋路堤的荷载传递的理论分析进行了改进,最后得到了桩土应力比和桩土差异沉降的计算式。本文理论计算值与工程实例实测值对应很好,且网上网下桩土应力比能反映出加筋垫层网材的拉膜效应作用。因此,本研究能为柔性桩承式加筋路堤的设计及施工提供一定的参考。

| Abstract: | Based on the literature1],considered the skin friction on reinforcement of deformable pile-supported and geosynthetics-reinforced embankments（abbreviated to DPGE）,new formulas of pile soil differences pile-soil stress ratios and pile-soil differential settlement are deduced by improved load transfer model of DPGE.This paper calculated theoretic value is very close to observation of practical engineering,and the pile-soil stress ratios of above and under reinforcement reflected tensioned membrane effect of reinforced cushion in DPGE.Therefore,this research results provides definite reference to design and constructing of DPGE for the future. |
