The fatigue life of cement-sodium-silicate-grouted soil is considerably affected by loading amplitude and frequency, but the effect of former is stronger than that of latter.
荷载振幅与荷载频率直接影响着水泥加固土的疲劳寿命，但荷载振幅比荷载频率对疲劳寿命的影响大得多。

The fatigue behavior of cement-sodium-silicate-grouted soil is investigated by cyclic loading test of dynamic asymmetric sine wave load.
采用载荷控制、非对称正弦波动态载荷变化方式对水泥土进行疲劳载荷试验。
