Abstract

The present study focuses on input loss of deeply embedded foundations that support bridges and viaducts. In recent years, deeply embedded foundations have been longer and of various diameters so that flexural movement of sidewalls presumably dominates in the foundations. Therefore, it is highly necessary to investigate the influence of the flexible sidewall on input loss. In the previous studies, however, the characteristic of input loss has been frequently evaluated under perfectly or compatibly rigid body conditions. Therefore, the present study reveals the characteristic of input loss affected due to the flexibility by means of a closed form solution derived based on a three-dimensional wave propagation theory.
