Beitrag zur dreidimensionalen numerischen Berechnung der Wellenausbreitung und -abschirmung im elastischen Halbraum
… foundations against surface waves is the passive trench. In order to examine the function of the trench the propagation will be simulated in this research numerically with the aid of the boundary element method. The calculation takes place in a three dimensional system, because only so the waves …

Reduction in ground vibrations by the use of wave obstacles
… here by use of numerical simulations, trenches and shaped landscapes being considered as wave obstacles. The effects of geometric parameters on open trenches, material parameters of filled trenches, and of infiltrated water in open trenches, were examined in appended Paper A. The finite …
