摘要
通过扩展基础加筋风稍砂地基的室内模型上拔试验,研究了不同试验方案的加筋土体在上拔荷载作用下的位移、极限上拔荷载、土体破坏形态以及土中应力,在分析和研究的基础上提出了加筋风积砂土体的上拔机理.
After studing test projects,indoor model uplift tests on the spread foundation of reinforced aeolian sand subgrade have been done.Displacement,ultimate uplift load,faiture surface and inner stress of reinforced earth is studied and analysed.Based on these studies,the mechanism of uplift has been put forward.
