Abstract

As an economical and environmentally friendly corrosion-resistant lightweight filler material, rubberized cemented soil has many application prospects in coastal port engineering and lighthouse foundation construction. Based on the resonant column test, we investigate the dynamic properties of rubberized cemented soil under different rubber content, cement content, and surrounding pressure and focus on the influence of each influencing factor on its dynamic shear modulus and damping ratio. Test results show that the cumulative axial strain of rubberized cemented soil under consolidation pressure increases with the increase of rubber content and surrounding pressure and decreases with the increase of cement content. The degree of attenuation of the dynamic shear modulus curve of rubberized cemented soil decreases with the increase of rubber content and the decrease of cement content, and the non-linear characteristic decreases while it is less affected by the surrounding pressure. The maximum dynamic shear modulus decreases with the increase of rubber content and increases with the increase of cement content and surrounding pressure. When the rubber content is low, or the cement content is high, the maximum dynamic shear modulus is most affected by the content change. The rubber admixture slows down the dynamic shear modulus's decay and promotes its earlier decay at lower surrounding pressure. A decrease in cement content and increase in surrounding pressure delay the decay and make the decay relatively larger. The damping ratio increases monotonically with the increase of dynamic shear strain. Increasing the rubber content and decreasing the surrounding pressure will increase the damping ratio. When the cement content is less than 15%, the damping ratio increases with the increase of cement content, while when the cement content is more than 15%, the damping ratio decreases instead.
