| Abstract: | The nonlinear bifurcation for the riser under the effect including tension, ovcrpull and steady flow, is discussed. The singular perturbation method is employed to solve the perturbed bifurcation problem with multiple independent parameters. Bifurcation curve surfaces which model imperfections aer obtained. Their stab ility is also investigated. |
