| 内容記述 | This paper presents the experimental and theoretical studies on deformation and failure behaviours of the typical weak and hard rocks for conventional triaxial tests under monotone and "weakly" cyclic loadings. These materials show the dilation characteristics at lower confining pressures and the brittle-ductile transition. We present a non-associated plasticity theory using a dilatancy function for plastic behaviour under monotone loading, and an extended multi-response theory to elasto-plastic behaviour under "weakly" cyclic loading. In these approaches, we treat only the strain hardening response of geomaterials as the material behaviour and do not apply them to the strain-softening response since the softening is a structural phenomenon rather than a material characteristic. We present the response functions by a Laplace trasformation. The response models are applied to simulate the behaviours of Oya-tuff under monotone loading with non-linear plastic response, and the behaviours of Funyu-tuff and granite under cyclic loading with non-linear elastic and plastic responses, respectively. We also describe a procedure for conventional triaxial tests of rock materials by a stiff testing machine, a closed measurement-analysis-system for a laboratory test performed by a microcomputer and a data banking system of rock triaxial tests. | |||||
