Abstract: A kind of catamaran crane with hoisting truss as connecting bridge structure has recently emerged on Qiantang River due to the prominent requirement of lifting and salvage in inland river and the difficulty of ship repair imposed by the situation of more ships than factories. The strength check of this new structure that is beyond the rules is a new problem in the ship inspection and certification. On the basis of relevant specifications, the analysis methods of the total longitudinal and local strength, total transverse and torsional strength, hoisting truss strength and supporting structure strength for this type of ship are presented and applied to the structural analysis of a 700 t crane ship. This method can be applied to the design and check of the same type of ship.

摘要： 由于内河起重打捞业务需求和船多厂少修船难情况突出,钱塘江上新近出现了一种起重桁架兼作连接桥结构的双体起重船。对这种超规范的新型结构,其强度校核是船舶检验发证的新问题。论文在相关规范的基础上,提出了该船型的总纵及局部强度、总横及扭转强度,起重桁架强度以及支撑结构强度分析方法,并应用于1艘700 t排水量的起重船进行结构分析计算。该方法可用于同类型船舶的设计与校核。
