    Abstract
    Seismic-induced pore pressure and effective stresses in the saturated porous seabed under seismic loading are the main factors that govern the overall stability of submarine pipelines. In most of the previous investigations for the seismic-induced dynamic response around a submarine pipeline have been limited to two-dimension cases. In this paper, a three-dimensional finite element model including buried pipeline is established by extending DYNE3WAC. Based on the numerical model presented, the effects of pipeline geometry and soil characteristics on the seismic-induced pore pressure of the seabed and internal stresses of ...

    Seismic-induced pore pressure and effective stresses in the saturated porous seabed under seismic loading are the main factors that govern the overall stability of submarine pipelines. In most of the previous investigations for the seismic-induced dynamic response around a submarine pipeline have been limited to two-dimension cases. In this paper, a three-dimensional finite element model including buried pipeline is established by extending DYNE3WAC. Based on the numerical model presented, the effects of pipeline geometry and soil characteristics on the seismic-induced pore pressure of the seabed and internal stresses of submarine pipeline will be discussed in detail.
