It is important to consider an aseismic issue

which is that transflective properties of the seismic wave propagating through joints embedded in rock in underground rock engineering. However

there is very limited research on transflective properties by using the continuously yielding nonlinear joints model. In this paper

a continuously yielding (CY) model was developed based on the time-domain recursive method (TDRM) for S wave using a nonlinear Coulomb-slip (MC) model. Verification of TDRM-based results was conducted in comparison with the simulated results via 3DEC code. Meanwhile

the influence parameters were also discussed. Finally

the results from MC model and CY model were compared under an idealised impulse excitation and a real ground motion record

respectively. It can be seen that TDRM-based results show good agreement with the simulated results by 3DEC

which proves that TDRM is reliable to study the subsequent parameters. In addition

CY model is significantly influenced by parameters of normal stress

incident wave amplitude

initial joint stiffness and joint spacing

respectively. Compared with MC model

CY model can better describe complex joint behaviours in the wave propagation

such as tangential stiffness degradation

shear strength deterioration

normal stress dependence and the hysteresis effect. Therefore

research results can provide useful references for the seismic design and analysis of rock underground engineering.
