Abstract: In the case of wave interactions with structural weakness planes in rook mass the results of reflection and refraction of waves at entirely cohesive boundaries have been used all along. But, oblique incidences of compressive stress waves at the structural weakness plane may result in relative slippage of rocks on both sides of the plane. The authors have derived the reflection and refraction coefficients for plane stress waves generated by blasting incidents on the structural weakness plane in rook mass according to its special boundary condition. The formula of energy dissipation and some computational results at the structural weakness plane are obtained. On the above basis, some problems about rook and soil engineering are discussed.
