Abstract : Two dimensional steady state solutions for a half-space subjected to uniform surface loads which move with superseismic speeds have been formulated for a Cap Model, recently developed for soils. The solutions require only quadratures, and were developed to have an independent check on solutions obtained by computer using either two dimensional finite differences, or finite elements. By going to the limit, when the speed V of the applied load approaches infinity, problems of one dimensional wave propagation are also solved when an additional, uniform load is applied to the surface of a half-space. Graphical and/or numerical results for a numer of situations are given. They can be used directly to check new computer based codes under development. (Author)
