By shifting the mean stress and the sinewave stress amplitude, uniaxial cyclic experiments were performed to study the dynamic response of fluid-saturated sandstones and marbles.
在单轴循环加载实验中不断改变平均应力和正弦波应力振幅的实验条件下，研究饱和砂岩和大理岩的动态响应。

Then, a semi-analytical solution for the velocity response of the pile subjected to a semi-sinewave exciting force was derived by using invert Fourier transform.
