Numerical Investigation on Screening Surface Waves Using a Buried Trench with Plate
This article is aimed at studying the effectiveness of a buried trench with a plate in screening the ground vibrations. Influence of various geometrical parameters normalized by Rayleigh wavelength is investigated to identify key parameters of the buried trench. Three types of the buried barriers depending on the relative position between plate and trench are considered herein: (a) trench with source-oriented plate, (b) T-shape trench and (c) trench with receiver-oriented plate. Screening effectiveness of these cases is compared to that of the buried trench without a plate. Parameters study shows that adding a plate to buried trench has a considerable beneficial effect on screening vibrations, and some design considerations of the buried trench with the plate are made for enhancing the screening efficiency.
