Cnoidal Water Wave Induced Pore Pressure Accumulation in the Seabed

ZHU Jieran

Abstract


The pore water pressure accumulation in the seabed soil under cnoidal water waves is examined in detail. The cnoidal water wave theory is employed to calculating the water pressure on the double-layer seabed in shallow water region. The modified Terzaghi consolidation equation is the governing equation. A general analytical solution for the consolidation equation is given in an integral form. And a comparative study is carried out to verify the two previous pore pressure generation models: the linear relation and the hyperbola model. Accordingly, a joint model is presented to analysis the pore pressure accumulation in seabed and the soil liquefaction in a practical accident happened in China Shengli Oil Field.
Key words: Cnoidal water wave; Pore pressure accumulation; Hyperbola model; Modified Terzaghi consolidation equation

Keywords
