boundary element method applied to simulate the seismic response of slope topographies on underground cavities for incident p, sv waves

This paper presents results of numerical analyses for the seismic response of slope type topographies in an elastic medium, under vertically incident sv and p seismic waves by boundary element method (bem). due to the complexity of this matter, few studies have been performed in this field. in this regard, a 2-d scattering and diffraction of plane p andsv waves induced by slopes above underground cavities and slope-cavity interaction are proposed. to show the interaction between them, a parametric analysis is carried out in the time-domain by be approach.
