UPLIFT MODEL TEST AND MECHANISM STUDY OF THE SPREAD FOUNDATION OF REINFORCED AEOLIAN SAND SUBGRADE

After studing test projects,indoor model uplift tests on the spread foundation of reinforced aeolian sand subgrade have been done.Displacement,ultimate uplift load,faiture surface and inner stress of reinforced earth is studied and analysed.Based on these studies,the mechanism of uplift has been put forward.
