Study on the Constitutive Model for Jointed Rock Mass
Fig 11
The results of experiment and numerical simulation((a) The failure mode of first rock mass sample in jointed rock direct shear experiment (the visual angles β0 of joints = 0°);(b) The contour for equivalent plastic deviator strain calculated by proposed constitutive model(the visual angles β0 of joints = 0°);(c) The failure mode of of second rock mass sample in jointed rock direct shear experiment (the visual angles β0 of joints = 30°); (d)The contour for equivalent plastic deviator strain calculated by proposed constitutive model(the visual angles β0 of joints = 30°))
