Abstract:
Theoretical investigation on incident S-wave propagating across single rock joint with consideration of shear slide
behavior is presented by using a full time-domain algorithm.Shear slip model is established in the paper,and then the
wave propagation equations are deduced when the rock joint is subjected to obliquely incident S-wave.Based on the numerical
 results deduced from the suggested method,parametric studies for oblique incident S-wave are carried out.The
results indicated that the wave propagation equations derived in the present study have the virtue of convenience to consider
 the shear slide behavior of rock joint without complicated mathematical methods such as Fourier and inverse Fourier
transforms.By parametric studies,it is found that the propagation rule and the energy-transmitted rule are greatly influenced
 by shear slide behavior.To solve the practical rock engineering problem,theoretical models proposed will be an effective
 approach in analyzing the propagation characteristic of stress wave in jointed rock.
