为探究半潜船初稳性高度（ GM）限值的影响因素及其作用机理，对常规的动平衡公式做了分析改进，基于特重大件的装载特点，建立了半潜船初稳性高度安全限值的理论计算公式。通过变参数分析法定量计算了特重大件的质量、重心高度、受风面积、风压中心位置、海上风速、摩擦系数等参数对半潜船初稳性高度安全限值的影响程度，进而揭示各影响因素对初稳性高度安全限值的影响规律。最后结合半潜船载运特重大件实际案例，计算分析了各因素变化对半潜船初稳性高度限值的影响规律，证明了所提出的半潜船初稳性高度安全限值理论计算方法的合理性。

To explore the influencing factors of semi?submersible vessel’ s metacentric height limits and their mecha?nisms, the original dynamic balance formula was modified to form a new formula suitable for semi?submersible ves?sel’ s metacentric height limits. By this method of the variable control parameters, the parameters including special heavy cargo’ s weight, height of center of gravity, wind area, height of wind pressure center, wind speed on the sea, friction coefficient, etc. were changed to quantitatively calculate their influencing degree on the metacentric height limits of semi?submersible vessels. Finally, the changing rules of semi?submersible vessel ’ s metacentric height limits were analyzed under different influencing factors in combination with the practical status of special heavy cargo, verifying that the formula for the metacentric height limits is reasonable.
