摘要: 本文利用英国GDS公司生产的RCA共振柱系统测试海洋含黏粒砂土动剪切模量,同时对比纯砂样的动剪切模量,系统研究固结应力、初始密实度、黏粒含量等因素对砂土最大动剪切模量的影响。试验结果表明:最大动剪切模量随有效固结应力增大而增大;随初始密实度增大而增大;随黏粒含量的增加而降低。

关键词: 共振柱试验, 黏粒, 最大动剪切模量, 骨架孔隙比

Abstract: Dynamic shear modulus in marine clay containing sand was tested using RCA resonant column test system produced by GDS Company of UK. At the same time, comparing to the dynamic shear modulus in pure sand sample, the various factors such as the consolidation pressure, initial compactness, clay content, etc. influencing the maximum dynamic shear modulus of soil were studied systematically.The results show that the maximum dynamic shear modulus increases along with the effective consolidation pressure increasing and the initial density increasing, while it decreases along with the clay content increasing.

Key words: resonant column test, clay, maximum dynamic shear modulus, skeleton void ratio
