关于土的本构模型中误差探讨

Discuss about the error in constitutive model of soil

在处理试验数据过程中发现通过一定的数学换算,可以将试验数据与土的双曲本构模型拟合度提高,相关系数增大,其实在某种意义上这是一种假象,不仅在数学理论上进行分析与阐述并且用实例进行验证。

In data processing course author found through a certain mathematical manipulation the goodness of fit and correlation between test data and hyperbolic constitutive model of soil can be improved. In fact this is a deceptive phenomenon. In view of this mathematic theoretical analysis is made, which is also verified combined with examples.
