| 摘 要： | 不同地震荷载对黄土的动力特性有着重要影响。本文利用微机与我们组装的DSD160型电磁式振动三轴仪组成的一个可对试样施加任意波轴向荷载的动三轴试验系统，对黄土在不同地震荷载下的动模量和阻尼比进行了对比试验研究，初步得到了不同地震荷载对一组黄土的动模量及阻尼比影响的一些结果。

| Abstract: | The dynamic properties of loess are greatly affected by different seismic loadings.In this paper,a system of combining a microcomputer with an electromagnetic dynamic triaxial apparatus of DSD160 model assembled by us was developed,which can apply an axial load of arbitrary waveform on aspecimen.The dynamic moduli and damping ratio under different seismic loadings were comparativelystudied in a laboratory.Some initial results in the effect of different seismic loadings on dynamic mod-ulus and damping ratio of loess were obtained. |
