| 摘 要： | 应用共振柱仪对厦门软粘土剪切模量和阻尼比进行了试验研究。试验结果表明：剪切模量随着剪应变的增加而逐渐减小；围压越大，剪切模量越大；阻尼比随着剪应变的增加而增加；围压越大，阻尼比越小；动剪切模量与阻尼比的变化比较小。根据试验结果，建立了剪切模量和阻尼比的经验公式。

| Abstract: | Shear modulus and damping ratio of the soft clay were studied by means of resonant column test.The results of experiments show that shear modulus decreases as shear strain increase,and shear modulus increases when consolidation pressure rises.Damping ratio grows as shear strain gains.When consolidation pressure increases,damping ratio reduces.Shear modulus and damping ratio change very little.Formulas of shear modulus and damping ratio were established. |
