Abstract : The author examines the conditions of propagation of longitudinal seismic waves through a layer, considering the possible effect of such waves on man-made structures, particularly gravity dams. Several models for the layer and various boundary conditions are studied, and equations are derived to express the stress states in the layer. Plastic waves as well as elastic waves are considered. Gravity of different dimensions and geometry are assumed in seeking quantitative evaluation of the effects of seismic waves. Use of the formulas permits one to study the stress state of the layer along which longitudinal waves pass even when the physical characteristics of the layer and the conditions at the boundaries are complex. Interaction of the waves with man-made structures may be evaluated quantitatively. Precision of computation depends on the model used, and this precision may be improved if one is willing to increase the volume of computations. Examples support the view that the results may be used for engineering calculations, though they are still preliminary and represent approximations rather than final solutions. (Author)
