摘要
桩承加筋路堤提高地基的承载力、减小沉降和差异沉降,减小路基的侧向变形,提高桩土荷载分担比,降低工程成本,应用越来越广泛。本文以一个路堤工程为原型,采用Plaxis 8．2软件,利用拉格朗日大变形的分析方法,研究软土地基上的桩承加筋路堤的变形性状。分析了加筋材料的抗拉刚度、加筋的布置方式、桩间距和桩身刚度对桩承加筋路堤性状的影响。
Based on a piled embankment project case, the finite element analysis software, Plaxis 8.2, and Lagrange＇s large deformation analysis method are used to investigate the behavior of GRPS embankment. The influence of design parameters, such as tensile stiffness of reinforced materials, the position of the reinforcement bars, the spacing of piles and stiffness of pile bodies on performance of reinforced embankment over piles are discussed.
