Abstract
The dynamic properties of lime-solidified soft soil affect the safety and function of buildings. In this study, lime was used to solidify soft soil from the Binhai New District of Tianjin, China. A dynamic triaxial testing system was used to measure the dynamic stress-strain curves of solidified soft soil samples for different lime mixing ratios and confining pressures. The relationship between the dynamic strength and the static strength, the influence of the lime mixing ratio on the dynamic strength, and the variation of the dynamic shear modulus G and the damping ratio λ were analyzed. The results show that under static and dynamic loads, the internal friction angles of the lime-solidified soft soil are almost the same and range between 21.72° and 24.42°. Different cohesion values are obtained under static and dynamic loads, and these two values increase and approach each other with increasing lime mixing ratios. G and λ depend on the shear strain, the lime mixing ratio, and the confining pressure. These results serve as a reference for the formulation of a solidification scheme for soft soil.
