摘要
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。
Considering the basic characteristics of soil stress -strain relationship revealed by the results of the soil dynamic tests,a simple and reasonable functional formula of the skeleton curve and the dynamic skeleton curve in the shear stress -strain relationship of soil is suggested in this paper , and by introducing the formula into the dynamic skeleton curve model of soil dynamic shear stress -strain relationship,a simple empirical functional formula of soil dynamic shear stress -strain relationship is led to. This formula can fit the experimental damping values of soil and is convenient to application.
