Effects of Wave Non-Linearity on the Wave-Induced Response of Soil and Buried Pipeline: Application of GFEM-WSSI
|出版社:||國立中興大學工學院;Airiti Press Inc.|
Design of a submarine pipeline regarding its stability is an important task for coastal geotechnical engineers. Most previous investigations have only concerned with the soil response around a buried pipeline due to linear progressive ocean wavers, even though the linear wave theory has been reported to be only valid for small amplitude waves in the literature. In this paper, the general finite element model for the wave-seabed-structure interaction (GFME-WSSI) proposed by the first author is adopted to investigate the interaction between non-linear ocean waves, a buried pipeline and a porous seabed. Based on the proposed model, a parametric study is performed to investigate the effects of wave non-linearity and pipe thickness on the pore pressure and internal stresses around the pipeline. Numerical results show that the influence of non-linear wave components is not always negligible without substantial error, especially for large wave steepness in shallow water. Moreover, the internal stresses within the buried pipeline increase significantly as the thickness of the pipeline decreases.
