Experimental study on dynamic characteristics of structural soft clay under different vibration frequencies

open access: yesYantu gongcheng xuebao, 2017
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
