风积沙的压实特性与循环荷载下变形性状的试验研究
Compaction property of eolian sand and its deformation behavior under cyclic loading
【摘要】 在对风积沙压实特性进行分析的基础上 ,探讨了含水量对风积沙压实影响的机理。通过动三轴试验 ,得到了影响循环荷载下风积沙变形特性的主要因素为压实含水量、循环应力比和围压
【Abstract】 Based on the analysis of compaction property about eolian sand,this paper makes an approach to the influential mechanism of water content on eolian sand compaction.According to the dynamics triaxial test on the eolian sand,the strain property under cyclic loading is mainly affected by the compaction water content,cyclic stress ratio and ambient stress.
