| 摘 要： | 以拟建大（同）～西（安）客运专线为例，选取典型黄土地段，采集原状马兰黄土和离石黄土进行室内常规试验和动三轴试验，研究了长持时、小振幅作用下黄土振陷特性，通过三组比较试验，得出了黄土振陷与动荷载、埋深、振次、振动频率的定性关系，并对振陷机理做了探讨。

| Abstract: | As an example of new passenger railway to be constructed from Da'tong to Xi'an,selecting the typical loess sections,taking original Malan and Lishi loess sample for indoor routine tests and dynamic triaxial test,studying the characteristics of loess subsidence under the action of long-lend,small amplitude vibration.We conclude the qualitative relationship of subsidence about dynamical loads,depth,vibration time,vibration frequency by three group comparison test,than do a certain amount of the mechanism of l... |
