The dynamic resilience modulus of reinforced subgrade is an important design index of reinforced soil techniques in road engineering.In this paper, the dynamic resilience modulus test of geogrid-reinforced gravel soil was carried out by dynamic triaxial apparatus, and the influence pattern of water content, reinforcement mode, the shear and lateral influence characterization in the dynamic resilience modulus were comparatively analyzed.The prediction model parameters for dynamic resilience modulus were analyzed by regression. Experimental results showed that the dynamic resilience modulus of reinforced soil reduced with increase of moisture content.The geogrid should be laid in the horizontal shear deformation layer in the soil, the dynamic resilience modulus could be considerably improved by increasing the number of reinforcement layers or reducing the spacing of layers.When other conditions remained unchanged, the dynamic resilience modulus increased with the increase of shear and lateral influence characterization. The parameter regression results of the NCHRP 1-28A model were satisfactory, the model could be used to predict the dynamic resilience modulus of geogrid-reinforced reinforced soil.
