摘　　要：研究了绞吸式挖泥船定位桩拔桩力的计算方法,比较了API-RP2A与非线性有限元模拟分析的计算方法,两者的结果与实际情况符合较好。并进一步讨论了拔桩过程中桩侧摩擦阻力的各种影响因素,有一定的推广实用价值。The paper discusses the method of calculating spud-lifting force for cutter suction dredgers. API-RP 2A method and no-linear finite element method have been used to calculate the spud-lifting force which agrees well with the real case. The factors that can influence the spud-lifting process have also been further discussed, it worth widely spread.
