摘要
作者以损伤理论为基础,建立了非饱和原状黄土的非线性损伤本构模型,模型可反映原状非饱和黄土独特的力学特性。该模型共包含13个参数,都可以通过试验测定。该模型进一步揭示了非饱和土体中某些应力应变特性的内在规律,从而把非饱和黄土的本构模型研究推到了一个新的水平。
Based on the damage theory, a nonlinear damage constitutive model of unsaturated undisturbed loess was developed. The model can describe the complex mechanical behaviors of unsaturated loess. There are 13 parameters in the constitutive model which can be determined from the test. The model revealed some inherent law in the stress-strain behavior of unsaturated loess. The above research develops the constitutive model of unsaturated loess to a new level.
