摘　　要：长江沿岸船厂承建的大型集装箱船为了能够安全通过跨江大桥,通常将上层建筑拆分为上、下两部分来降低其自身净空高度,并借助拖轮实现拖航过桥,但也因此产生昂贵的拖航费用并导致较长的上建复装工时。文中提出了新型的全封闭驾驶室升降结构设计方案,可实现大型集装箱船自航通过跨江大桥,大幅节省过桥费用和工时;此外,还通过有限元方法评估了该型全封闭驾驶室升降结构的强度和驾驶甲板、窗框结构的变形量,验证了该设计方案的安全性以及建造施工可行性。该文可为净空高度较大的船舶实现自航过桥提供设计参考。To safely pass through the cross-river bridge,the large container ships built by shipyards along the Yangtze River are usually split into upper and lower parts to reduce their clearance height and towed across the bridge by tugboats from the Maritime Bureau.This method leads to expensive towing costs and longer hours for the reassembly of the superstructure.A new design scheme for the jack-up structure of a fully enclosed bridge is proposed for the self-propelled bridge crossing of the large container ships,greatly saving the costs and time.Additionally,the strength of the jack-up structure and the deformation of the navigation deck and window frame of the fully enclosed bridge are evaluated by using the Finite Element Method,verifying the safety and construction feasibility of the design scheme.This article can provide design references for ships with large clearance heights to achieve self-navigation under bridges.
