本文介绍了一种典型的各向异性岩石--图恩迈尔页岩的力学行为的实验室研究。流体静压可压缩性测试可以表征材料的结构各向异性。进行了包括卸载循环在内的三轴压缩试验。研究了各向异性弹性响应、塑性变形和破坏行为。页岩的弹性行为是非线性的，页岩表现出大的各向异性塑性变形。页岩的破坏行为是各向异性的，并且强烈地依赖于围压和加载方向。(C)1997年爱思唯尔科学有限公司。
This paper presents laboratory investigations of the mechanical behaviour of a typical anisotropic rock: Tournemire shale. Hydrostatic compressibility tests allowed characterization of the structural anisotropy of the material. Triaxial compression tests, including unloading cycles, were performed. Anisotropic elastic response, plastic deformation and failure behaviour have been investigated. The elastic behaviour of the shale is non-linear and the shale exhibits large anisotropic plastic deformation. The failure behaviour of the shale is anisotropic and strongly depends on confining pressure and loading orientation. (C) 1997 Elsevier Science Ltd.
