扩展基础加筋风积砂地基室内模型试验研究

Study of indoor model test of spread foundation on the reinforced aeolian sand subgrade

摘要: 对扩展基础加筋风积砂地基进行室内模型试验研究,分析了不同布筋方式下加筋风积砂土体在下压荷载作用下的应力场、变形、破坏模式及承载力变化规律,提出加筋风积砂土体在下压荷载作用下的强度机理,并比较各种布筋方式的适用性。

Abstract: Based on the indoor model test of spread foundation on reinforced aeolian sand subgrade,the variation of the bearing capacity,the displacement,the surface of fracture and the internal stress of soil under pushdown load have been analyzed.Then the respective applications of different design have been compared.
