| Abstract: | Influence of factors such as cement-mixed ratio and confining pressure on the dynamic properties of composite specimen with soil cement was studied under a wide range of strains by regression analysis, a simple method for calculating the dynamic elastic modulus and damping ratio is proposed and an empirical formula considering the mentioned factors above is also presented to provide a elementary reference for aseismic design of composite foundations with cement-mixing piles. |

| Keywords: | composite foundation dynamic triaxial test cement-mixing ratio dynamic properties empirical equation |
