摘　　要：随着航运业的发展,浮船坞作为海上移动平台对船舶修建维护具有广泛的应用前景。为了满足市场需求,对原浮船坞增设艏艉压载舱、首部延伸平台和局部坞墙等结构,用以增加本坞的设计举力、作业面积等。由于该船坞艏艉外飘部分以及与外飘相连部分是结构强度的薄弱区,为了确保浮船坞在使用作业工况下的结构强度,对坞体结构进行了三维有限元强度计算,分析了坞体结构的应力分布。结果表明,改装后的浮船坞两次进坞工况和5000 t浮船坞本身受坞墩压力工况的最大结构应力均小于钢板屈服应力,且安全系数分别为1.68、1.72和2.48,均满足强度要求。同时还提出了作业中可适当加密布墩等实际施工措施,来保障作业的安全性与可靠性,旨在为后续我国浮船坞的大型化设计与校核提供参考。With the development of shipping industry,the floating dock has a wide range of applications as a mobile platform for ship construction and maintenance.In order to meet the market demand,the original floating dock is equipped with additional structures such as bow and stern ballast tanks,bow extension platforms and partial dock walls to increase the designed lifting capacity and operating area of the dock.Since the floating part of the dock and the part connected with the floating part are the weak areas of structural strength,in order to ensure the structural strength of the floating dock under the operating conditions,three-dimensional finite element strength calculations are carried out to analyze the stress distribution of the dock structure.The results show that the maximum structural stresses of the modified floating dock in two docking conditions and the 5000 t floating dock itself subjected to the dock pier pressure condition are less than the yield stress of the steel plate,and the safety coefficients are 1.68,1.72 and 2.48,respectively,which meet the strength requirements.At the same time,it also puts forward the actual construction measures such as appropriate densification of piers to ensure the safety and reliability of the operation.It aims to provide reference for the subsequent large-scale design and calibration of floating docks in China.
