--- res: bibo_abstract: - A boundary element model of a tunnel running through horizontally layered soil with anisotropic material properties is presented. Since there is no analytical fundamental solution for wave propagation inside a layered orthotropic medium in 3D, the fundamental displacements and stresses have to be calculated numerically. In our model this is done in the Fourier domain with respect to space and time. The assumption of a straight tunnel with infinite extension in the x direction makes it possible to decouple the system for every wave number kx, leading to a 2.5D-problem, which is suited for parallel computation. The special form of the fundamental solution, resulting from our Fourier ansatz, and the fact, that the calculation of the boundary integral equation is performed in the Fourier domain, enhances the stability and efficiency of the numerical calculations.@eng bibo_authorlist: - foaf_Person: foaf_givenName: Georg foaf_name: Rieckh, Georg foaf_surname: Rieckh foaf_workInfoHomepage: http://www.librecat.org/personId=34DA8BD6-F248-11E8-B48F-1D18A9856A87 - foaf_Person: foaf_givenName: Wolfgang foaf_name: Kreuzer, Wolfgang foaf_surname: Kreuzer - foaf_Person: foaf_givenName: Holger foaf_name: Waubke, Holger foaf_surname: Waubke - foaf_Person: foaf_givenName: Peter foaf_name: Balazs, Peter foaf_surname: Balazs bibo_doi: 10.1016/j.enganabound.2011.12.014 bibo_issue: '6' bibo_volume: 36 dct_date: 2012^xs_gYear dct_language: eng dct_publisher: Elsevier@ dct_title: A 2.5D-Fourier-BEM model for vibrations in a tunnel running through layered anisotropic soil@ ...
