摘要：

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.
