本文从线弹性材料力学理论出发，在本船波浪外载荷由模型试验得到并已确定的基础上，综合考虑结构弯曲、剪切载荷作用模式，对多分段坐底式起重工程驳船直接承受环境载荷的船体外板结构进行改造设计。从被改造母船的设计承载能力出发，综合考虑防波堤式直墙建筑物砰击载荷作用模式，全面研究承载构件的弯曲、剪切强度，进而有效推进多分段坐底式起重工程驳船的改造工程设计。
The paper studied structural strength about out hull scantlings of un-continuous bottom supported ship-type structures based on linear elastics theory about mechanics of materials. The target barge will operate on reef and the distance between reef ravine is variable, the loads for such un-continuous bottom supported ship-type structures are different from vertical-wall structures and common ship structures. The global wave forces caused by different environment conditions determined by model test and the grounded forces have been calculated by geostatics. The study focused on combination of bending and shear strength of out hull scantlings in this paper considering the direct action from wave loads and un-continuous bottom grounded forces. In the end, the study method can be applied to similar engineerings.
