摘要:
为探究细粒含量FC、孔隙比e以及初始有效围压σ3c对饱和砂类土小应变剪切模量Gmax的影响,对具有不同FC、eσ3c的饱和砂类土开展了一系列弯曲元试验。试验发现:当σ3c和FC均相同时,Gmaxe的增大而减小;当e和FC均相同时,Gmaxσ3c的增大而增大,当仅FC相同时,随σ3c的增大,Gmaxe增大而减小的速率基本保持不变,而当仅σ3c相同时,FC对Gmaxe增大而减小的速率影响显著。分析表明:当FC确定时,Hardin模型能很好的预测Gmax,但随FC的增大,模型参数A逐渐减小;基于等效骨架孔隙比的修正Hardin模型能较好预测具有不同FC、eσ3c的砂类土的Gmax,且Gmax预测值的误差基本小于10%。
