文章采用非线性时域方法进行内倾船型在横浪中横摇运动的数值预报，并在计算中考虑了船体瞬时湿表面变化对水动力的影响。在此基础上，通过对波浪时域历程下船舶的整个倾覆过程进行模拟计算，建立了船舶在瘫船状态下的倾覆概率计算方法。在耐波性水池进行了内倾船型在瘫船状态下的大幅极限运动模型试验，采用模型测试数据对计算结果进行了验证。对内倾船型在波浪中的倾覆特性进行了研究，得到不同海况下的倾覆概率和倾覆前的平均时间，并给出了内倾船型GM的建议取值。

In this research, the roll motion of tumblehome hull is forecasted numerically by a nonlinear time domain method considering hydrodynamic variation caused by the hull instaneous wet surface. The time his-tories of capsizing motion are simulated at time domain and the method of predicting capsizing probability under dead ship condition is established. Model test of the tumblehome hull for large amplitude motions un-der dead ship condition is carried out in the seakeeping basin and calculated results are verified by the model test data. The capsizing probability, the mean time before capsizing and the suggested GM value are obtained based on the investigation on the capsizing characteristic of the tumblehome hull.
