层状岩体横观各向同性弹塑性模型及数值实现
A transversely isotropic elastoplastic constitutive model for layered rock mass and its implementation
摘要
Abstract
With the differences between strength and deformation characteristics of the layered rock mass in parallel and perpendicular directions with respect to the bedding plane, view the layered rock mass as transversely isotropic medium in nonlinear analysis. On the basis of previous studies, a transversely isotropic elastoplastic constitutive model is given, and the model is embedded into ABAQUS with the UMAT program. By comparing the results of uniaxial compression tests of layered specimens with M-C model in ABAQUS and the transversely isotropic elastoplastic constitutive model to verify the validity and practicability of the model. In addition, the model degenerates into the isotropic model to calculate the stratified rock in underground engineering, the results show good agreement with the D-P model in ABAQUS, so this model can provide some guidance for studies of anisotropic properties of engineering research.关键词
