土体e-p曲线双曲线模型模型参数A的研究

Study on Model Parameter A of Hyperbolic Model of Soil e-p Curve

本文总结前人对土体的e-p压缩曲线双曲线模型的研究。利用万鹏等建立的新形式土体的e-p压缩曲线双曲线模型,通过拟合974组不同类别土体的e-p压缩曲线,建立不同类别土体模型参数A与含水率ω的分布图,总结分析土体类别、液性指数、含水率ω和模型参数A之间的内在联系,探究模型参数A的物理意义。对探究双曲线模型进一步发展指出新方向。

This paper summarizes the previous studies on the hyperbolic model of the e-p compression curve of soil.Using the hyperbolic model of the e-p compression curve of a new form of soil established by Wan Peng et al.,974 groups of e-p compression curves of different types of soil were fitted.The distribution diagrams of different types of soil model parameters A and moisture contentωare established,the internal relationship between soil types,liquidity index,moisture contentωand model parameter A is summarized and analyzed,and the physical meaning of model parameter A is explored.It points out a new direction for the further development of the hyperbolic model.
