在对隔水导管进行受力分析的基础上，拟合出风、波、流载荷随高度和深度变化的函数关系式。以某浅海油田工程为例，联合风、波、流的共同作用力，采用Workbench模拟导隔水管在最恶劣工况下屈曲响应和应力分布，得出隔水导管的临界失稳载荷与形变特点以及应力分布，指出结构薄弱环节；根据所得固有频率，算得各阶频率所对应共振转速。

Force applied to riser is analyzed. As for wind, waves and currents, the relationship between their load and their height and depth is work out. The relationship was applied to oil field engineering in shallow sea. Riser buckling response and stress distribu-tion in the harshest conditions were simulated on Workbench and the critical buckling load deformation characteristics and stress distri-bution were obtained. The structural weaknesses was pointed out. Corresponding to each order resonance speed, the frequency was cal-culated with the natural frequency.
