Abstract

Based on the Biots theory of consolidation, the model of the seabed-pipeline interaction is established using viscous-elastic artificial boundary in this paper. The distribution of the pore pressure in seabed soil and the dynamic response of submarine pipeline are studied under El Centro seismic wave by virtue of the general-purpose FEM analysis package ADINA. The effects of the elastic anisotropic soil and two-layered seabed behaviors on the seismic-induced pore pressure and internal stresses are discussed emphatically. It actually shows the validity and practicality of dynamic response of submarine pipeline under seismic loading. © 2008 Science Press Beijing and Springer-Verlag GmbH Berlin Heidelberg Geotechnical Engineering for Disaster Mitigation and Rehabilitation.
