- Abstract
The dynamic compressive modulus, damping ratios, dynamic intensity and other kinetic parameters of argillaceous slate cement-improved soil were studied using dynamic tri-axial test in this paper. The effects of confining pressure and loading frequency on these dynamic parameters were analyzed. By comparing the dynamic parameters of unimproved soil and improved soil, the improvement effect was analyzed and evaluated. Research shows that: i) the dynamic compressive modulus of cementimproved soil decreases with the increase of dynamic strain amplitude, the relationship between them is approximately a hyperbolic function; ii) the damping ratios increases with the increase of dynamic strain amplitude, the relationship between them is also approximately a hyperbolic function; iii) the initial dynamic compression modulus increases with the increase of confining pressure, while the maximum damping ratio decreases with the increase of confining pressure; iv) the initial dynamic compressive modulus increases with the loading frequency, but the loading frequency has little effect on the maximum damping ratio; v) the dynamic stress intensity is linear with the logarithm of failure cycle times, and the dynamic stress intensity decreases with the increase of the failure cycle times. The dynamic strength and the initial compressive modulus of argillite-slate soil have been significantly improved after the cement improvement while the maximum damping ratio changes little.
