Abstract
The response of a buried structure to a surface loading is analyzed by a re latively simplistic model, yet comprehensive enough to delineate both wave propagation phenomena and effects of soil arching. Analysis of a buried cir cular plate response under surface impulsive loading, according to this mod el (which shows a good agreement with the theoretical predictions to the ex perimental results) enables an insight to the problem's full range, from ve ry short impulse load to long, quasi-static loading. Application of this so lution to a study case shows that both wave propagation related phenomena a nd the arching phenomenon (related to relative displacements in the soil ab ove the structure) may be involved in the system's response to surface impa ct loading. Hence, a general analysis of a buried structure's response to d ynamic surface loading should consider not only the wave propagation effect s, but also take into account the soil arching effect.
