Wave propagation across rock masses and the induced ground motion have a great influence in the design and construction of underground cavern/tunnel constructions and mining activities. When arriving at the ground surface，the waves will cause the ground motion which is threatening to the stability and safety of the ground buildings. The present investigation was concerned with the interaction between the blast wave and a natural structural plane by using a time-domain recursive method. Based on the conservation of momentum at wave fronts，two types of interaction were analyzed first，i.e. the interaction between blast wave(i.e. longitudinal wave) and a linearly elastic structural plane，the interaction between stress waves(longitudinal wave or transverse wave) and a free surface. Next，wave propagation between a single structure plane and the ground surface was analyzed. Considering the time shifting function，the wave propagation equation for every wave arrival at the ground surface was established. On the basis of the derived wave propagation equations，the mathematical expressions were deduced for ground surface vibration caused by stress waves. As the result of the wave superposition，the particle velocity on the ground surface is subsequently obtained.
