| Abstract | The stability of a pipeline on the continental slope involves a complicated interaction between the pipe and the sloping seabed. Based on the Coulomb passive earth pressure theory, a theoretical pipe-soil interaction model is proposed for the instability of the anti-rolling pipeline on a sloping sandy seabed. The mechanisms of shallowly-spreading slippage and deeply-spreading slippage are discussed respectively. The theoretical model is verified with the existing experimental results. Parametric study indicates that the slope angle has much influence on the ultimate lateral soil resistance of the pipeline on a sloping sandy seabed. |
