Furthermore, the critical cyclic stress ratio is determined according to the time history curves of pore water pressure under different cyclic stress ratios.

此外由不同循环应力比下孔压时程曲线确定出临界循环应力比。

There is critical cyclic stress ratio of soft clay under cyclic loading. The value of critical cyclic stress ratio can also be obtained by pore water pressure curves.

循环荷载作用下饱和软黏土存在临界循环应力比，通过孔压也可以确定其值大小。

It is shown that the critical cyclic stress ratio of cement-soil pile composite foundation is bigger than that of saturated soft foundation and is not affected by cement mixing ratio basically.

试验结果表明，在循环荷载作用下复合地基同样存在临界循环应力比，其值大于单纯饱和软基的临界循环应力比，而且受水泥掺入比的影响不显著。
