不同频率影响下结构性软黏土动力特性试验研究
Experimental study on dynamic characteristics of structural soft clay under different vibration frequencies
摘要
Abstract
To study the influence of frequency on the dynamic characteristics of structural soft clay, a series of dynamic triaxial tests based on the two kinds of waveforms and different vibration frequencies are performed. The results show that when the vibration frequency is smaller and the deformation of the soil is larger, the deformation of the soft clay and permanent strain will be larger. Under the same conditions, the dynamic stress-strain softening degree of the square wave is higher than that of the sine wave. Under the same number of vibration, the pore pressure decreases with the increasing frequency. The effect of amplitude on the change of pore pressure is that the pore pressure increases fast and the stable value is larger when the amplitude is low.关键词
