| 摘 要： | 针对Hewlett土拱理论设计桩承式加筋路堤桩土应力比时没有考虑筋材作用的缺陷，在Hewlett土拱理论的基础上考虑筋材的作用，建立路堤土拱、筋材与路堤土体相互作用的力学模型，推导出考虑筋材作用下桩承式路堤桩土应力比的计算公式，并通过广梧高速公路一试验段工程实测数据的对比分析，验证了改进算法的合理性和可靠性。

| Abstract: | As the reinforcement effect has not been considered in Hewlett soil arch theory when designing pile-soil stress ratio of piled embankment,the mechanical model of soil arch,reinforcement material and soil mass interaction is established considering reinforcement effect based on Hewlett soil arch theory.Thus the calculation formula of pile-soil stress ratio of piled embankment considering reinforcement effect is educed.Through comparative analysis of measured data from a test section in Guangzhou-Wuzhou Expre... |
