Weight minimization of dynamically loaded 3-D foundation on layered medium
Minimum-weight design of a machine foundation on an inhomogeneous soil is considered. The soil model under the base of block corresponds to a layer with linearly varying properties overlying a uniform half-space. Furthermore, the block may be surrounded by a backfill. The optimal designs of dynamically loaded rectangular machine foundation, including coupled sliding-rocking vibrations, are found for a number of realistic inhomogeneous supporting media. The results obtained in the case of the layered soil are compared with those for a uniform half-space. It illustrates the problem of adequate modelling of the nature of the soil profile providing an insight into the action of the soil-foundation-machine system from the point of view of performance and safety.
