| 摘 要： | 现役船舶都存在船体构件的腐蚀问题，由于影响腐蚀的因素很多而且不确定，造成腐蚀对船舶总纵强度评估的不确定性。本文基于凸包理论，建立了评估不确定腐蚀情况下现役船舶最小剖面模数的数学模型，并以现役散货船为例，计算得到考虑腐蚀不确定情况下船体横剖面最小模数的极值范围。

| Abstract: | The thesis applies convex theory to calculate the uncertain minimum sectional modulus of ships in use and sets up a convex model of uncertain thickness of ship structural members.Choosing a bulk carrier as a typical example,the paper gets and evaluates the limits of its minimum sectional modulus considering uncertain thickness of ship structural members. |
