| 摘 要： | 本文对现有土的动应力－应变关系试验成果进行了分析和总结，推荐了用不同物性指标估算Ｇｍａｘ的经验公式，用塑性指数Ｉｐ描述Ｇ／Ｇｍａｘ－γ和λ－γ关系的经验曲线，并提出了用Ｉｐ为参数的Ｇｍａｘ、Ｇ／Ｇｍａｘ－γ和λ－γ曲线的经验公式，对工程应用颇有实用价值。

| Abstract: | In this paper the authors have analyzed the previous published test data of cyclic shear stress - strains relationship for various soils and recommended the empirical formulas of evaluating Cmax expressed as a funbtion of the various indexes of soil physical properties and the empirical charts between plasticity index IP versus both moduli reduction curves G/Gjmax and damping ratio curves Based on this,the authors have proposed empirical correlations between parameter IP versus Gmax,G/Gmax- and curves. These data will be great valuable to engineering practices. |
