AbstractA plane-strain finite element model is proposed to investigate the pipe-soil interaction mechanisms
for the partially embedded pipe with two kinds of constraint conditions, i.e. freely-laid pipe and anti-rolling
pipe. The numerical model is verified with updated mechanical-actuator experiments. The magnitude of lateralsoil-
resistance coefficient for the examined anti-rolling pipes is much lager than that for the freely-laid pipes,
indicating the end-constraint condition affects significantly the lateral stability of the untrenched pipeline in
ocean currents. Parametric study indicates that the variation of lateral-soil-resistance coefficient with the dimensionless
submerged weight of pipe is affected greatly by the internal friction angle of soil, pipe-soil friction
coefficient, etc.
