长江公路大桥梁段专用运输船设计研究

本文在大桥梁段运输系统论证的基础上，确定梁段专用运输船为双舵桨驱动及动力定位(锚泊辅助)的双体船方案，并就大桥梁段滚装过程受力分析、现场吊装动力定位方式以及运输船连结桥区域和甲板式舵桨区域的结构在设计中进行了综合考虑。

Design of Ship for Transporting Module of Highway Bridge over Yangtze River

Based on an adequate study of the transportation system for modules of a bridge to be built over the Yangtze River,it is determined to employ a catamaran which will be propelled with twin rudder-propellers and have a dynamically positioning system with an auxiliary anchor system.The stress that will occur from the process of the module's rolling-on and rolling-off is analyzed.The mode to dynamically position the catamaran during its operation in site and the special structures of the areas in which the deck-type rudder-propellers are mounted and the catamaran will be joined to the bridge are taken into account overall.
