An Obliquely Incident Wave Propagation Through the Jointed Complex Rock Masses

Abstract

Based on the wave function, the stresses and particle displacements on the joint are derived when the incident P-wave and S wave are obliquely incident to the jointed complex rock masses. And then, a modified time domain recursive method (MTDRM) is proposed. Based on the MTDRM, this paper investigates the P-wave and S-wave propagation crossing the jointed complex rock masses. The effects of the wave impedance ratios and the incident angles on the transmission and reflection coefficients are discussed. It is found that the wave crossing the jointed complex rock masses is not always attenuated but may be strengthened in some special cases.
