Abstract

Abstract

Taking geocell-reinforced saturated sand as research objects, the change laws of dynamic moduli of deformation, damping ratios of geocell-reinforced saturated sand with different reinforcement layers, geocell height, confining pressure and dynamic strain were studied. It was shown that the dynamic strain increased with the increase of dynamic stress in the same working condition, the increase of reinforcement contents could most obviously restrain the increase of dynamic strain. With the dynamic strain increase, the dynamic moduli of deformation decreased in the same working condition subjected to different confining pressure, the dynamic moduli of deformation under high confining pressure was larger. The damping ratios under the same working condition had no obvious rule with the increase of dynamic strain. The damping ratios under different working conditions decreased with the increase of dynamic strain subjected to confining pressure of 50 kPa and it tended to be contant after the dynamic strain exceeded a certain value.
- geocell,
- stress-strain relation,
- dynamic modulus of deformation,
- damping ratio
