2nd International Conference on Rock Dynamics and Applications (RocDyn), May 18-19, 2016, Suzhou, People's Republic of China© 2016 Taylor & Francis Group, London.A FEM-based numerical study is carried out to investigate the dynamic responses of underground openings in jointed rock masses. The heterogeneity and damage process of rocks are taken consideration in the numerical study. Effects of joint normal stiffness, joint spacing, joint orientation, amplitude of applied stress wave, cylindrical wave and tensile wave on the measured Peak Particle Velocity (PPV) around the tunnel are addressed. The simulation results show that the existence of joints has great influence on the stability of the underground tunnel. In addition, the cylindrical ...
