根据土体动力实验结果所示土体应力-应变关系的基本特征,本文提出了描述土体应力-应变骨架曲线及动态骨架曲线的一种简单合理的函数表达式,并将其引入作者建立的土体动力剪切动态骨架曲线应力-应变关系模型中,导出了能拟合土体实验阻尼值且形式简单合理、应用方便的土体动力剪切应力-应变关系的经验函数式。 According to the basic characteristics of the stress-strain relationship of the soil as shown in the soil dynamic test results, a simple and reasonable function expression describing the stress-strain skeleton curve and the dynamic skeleton curve of the soil is proposed and introduced into the author’s establishment. In the model of soil-dynamic shear dynamic skeleton curve stress-strain relationship, an empirical function formula that can be used to fit the experimental damping values ​​of soil and is simple and reasonable in form and convenient to apply has been derived.
