A Constitutive Model for Loess Considering the Characteristics of Structurality and Anisotropy

Soil Mechanics and Foundation Engineering Aims and scope

In this paper, a new model of undisturbed loess was presented based on the modified Cam-clay model with the structural and anisotropic parameters. The associated flow rule, combined with the consistency condition, was used to derive the incremental stress-strain relationship and establish a new model. The new model has a total of eight parameters, which can be obtained through routine labor tests. A triaxial test was conducted by selecting natural undisturbed loess. A comparison between the experimental results and calculated results shows that the new model is better than the modified Cam-clay model in simulating the stress-strain characteristics of natural undisturbed loess.
