振动排水条件下软黏土的渗透特性试验研究
Experimental study on permeability characteristics of soft clay under vibration drainage conditions
摘要
Abstract
In order to study the permeability characteristics of soft clay under vibration drainage conditions,vibration drainage consolidation instrument and variable head permeability test device were used to conduct permeability tests on soft clay under vibration drainage conditions,and the influence of load amplitude,frequency and void ratio on the permeability of soft clay was analyzed.The results show that the permeability coefficient of soft clay shows a trend of decreasing,then increasing and then decreasing with the increase of loading duration;the increase of permeability coefficient increases with the increase of loading amplitude;the increase of permeability coefficient at different frequencies is different in the middle of loading,and the highest increase is at 1 Hz;the e-k nonlinear expression is proposed for the vibration drainage condition,and the permeability coefficient decreases with the decrease of void ratio.The study can provide reference for the design and application of vibratory drainage consolidation method.关键词
