摘　　要：应用国际通用的概率破舱稳性理论对半潜船的分舱情况和破舱稳性进行初步分析。通过大量计算研究舱室垂向水平分隔限制、初始装载状态和边舱几何形状对分舱指数A的关系及影响,得到相关要素间的关系曲线图表和船舶设计指导原则。结合一艘半潜船破舱稳性概率方法的计算实例,针对概率衡准(SOLAS)做出计算结果的理论解释。最后给出半潜船的设计要素,对船舶设计初期指导压载水舱划分和评价概率破舱稳性具有参考价值。The ship subdivision and damage stability of semi-submersible vessels were studied by using worldwide general probability theory to the ship damage stability. After a number of computations, limit of compartment vertical separation, initial loading condition and geometry of side compartment were obtained and their relations and influences to the index A were established. The plots among related factors and general guidelines to ship design were generated. The computational results of stability requirement（SOLAS） were explained theoretically through an example of a semi-submersible vessel with probability calculation. Some design elements are listed which have value to evaluate index A in this paper.
