Abstract The fatigue behavior of cement-sodium-silicate-grouted soil is investigated by cyclic loading test of dynamic asymmetric sine wave load. Because of the progressive deformation of cement-sodium-silicate-grouted soil under cyclic load，the cement-sodium-silicate-grouted soil is damaged under a lower stress level. 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.

Key words： soil mechanics cement-sodium-silicate-grouted soil cyclic loading fatigue behavior
