Dynamic response in a poro-elastic ground induced by a moving air pressure. (English) Zbl 0553.73093

A steady-state theory is worked out for the dynamic response of a saturated poro-elastic ground to a pressure distribution travelling along the ground surface. A boundary layer approximation is applied to Biot’s equations for two phases. Sample results for supersonic, transonic and subsonic loads are presented.
