黄土湿载结构性本构模型的数值实现
Numerical Validation of Structural Constitutive Relationship of Loess with Moisture and Loading
摘要
Abstract
In this paper we propose a structural constitutive model of loess with moisture and loading. On this basis, we analyse the stress⁃strain relationship of structural loess by comparing the numerical simulation result with meas⁃ured result of natural loess. Results show that the model has the same features with Modified Cambridge model in describing saturated remodeled loess. The model could also simulate the macro⁃mechanics properties of remodeling loess with different water contents. Moreover, it is obviously superior to Cambridge model or Modified Cambridge model in describing the macro⁃mechanical properties of natural structural loess in laboratory. Finally we validate the rationality and accuracy of the model by comparing model results with conventional triaxial test results.关键词
