Abstract：The paper studies the free resonance vibration column test results of 189 Guangxi laterite samples by mathematical statistic methods. The results show that the variation of dynamic shear modulus ratio of Guangxi laterite in the middle strain range ( 5í10-4~1í10-3) is great with no law in damping ratio variability; in R software, the paper fits the experimental data in nonlinear way by using the Davidenkov model, and statistical data show good fitting effect, which an be used as recommended values for the dynamic nonlinear parameter of Guangxi laterite; it was indicated that the dynamic shear modulus ratio of Guangxi laterite was at middle level and the damping ratio of Guangxi laterite was smaller by comparing with the recommended value of cohesive soils in published articles.
