摘要

通过对泉州地区淤泥、粉质黏土、粉质黏土与粉砂互层土、残积土等4类典型土的共振柱试验,详细探讨围压大小、土的性质对这4类典型土的动剪切模量G及阻尼比γ的影响。通过试验和理论分析,给出泉州地区这4类典型土在不同围压下G/Gmax和λ/λmax随γ变化的平均曲线及其参数的推荐值,并定量给出围压对这4类典型土G/Gmax和λ/λmax随γ变化的平均曲线的参数的影响规律。
Through the resonant column test on the 4 sorts of typical soils as mud,silty caly,silty clay and silty sand interbedded strata,residual soil,the influence of confining pressure and soil property on dynamic shear modulus G and damping ratio γ of the 4 typical soils was explored in detail.By means of tests and theoretical analyses,the average curves of G/Gmax and λ/λmax with the change of γ under different confining pressures as well as their recommended values of parameters for the 4 sorts of typical soils in Quanzhou were presented.Besides,the influence patterns of the average curve parameters for G/Gma and λ/λmax of such 4 soils with the change of γ were also quantified.
