借助电镜扫描分析手段 ,对Q3 震陷性黄土的微结构特征、颗粒形态等进行了分析 .结果表明黄土的显微结构对震陷系数有较大影响 ,并与震陷的临界动应力关系密切 .通过孔隙含量的定量测试分析 ,探讨了中大孔隙对黄土震陷影响 ,并对土样的微结构某些指标进行了比较和分析
The microstructure characteristics and particle morphology of Q3 collapsible loess were analyzed by means of scanning electron microscopy.The results showed that the microstructure of loess had a great influence on the collapse coefficient and was closely related to the critical dynamic stress of the subsidence Through the quantitative analysis of the pore volume, the influence of the macropores on the loess seismicity was discussed, and some indexes of soil microstructure were compared and analyzed
