| 摘 要： | 该文以一艘80000t级整体式浮船坞拖航为例,从被拖物的角度对拖航工程设计的步骤及工作内容做了系统阐述;在此基础上,针对浮船坞的特点对浮船坞拖航的技术难点做了进一步的探讨。由于浮船坞的拖航阻力较大,拖力点的选取和拖力眼板的设计便成为浮船坞拖航设计的一项重要工作;鉴于浮船坞的强度校核关乎整个拖航工程的安全,该文利用有限元方法对浮船坞进行了整船有限元分析,既校核了拖航状态下的扭转强度、横向强度和局部强度,也对按规范进行的总纵强度校核做了进一步的验证。坞墙既高又窄的结构特点使得对坞吊进行就地有效封固成为一项特别困难的工作,为了节约将坞吊拆卸再安装的高额成本,对其进行了专门的绑扎设计。

| Abstract: | In this paper,the tasks and process of towing design is demonstrated from the point of view of the towed vessel,by taking the towage of an 80 000 DWT single unit floating dock as an example.The difficulties of towed floating dock are discussed.Since floating dock has a high resistance when being towed,the choice of tow point and the design choice of towing pad play important roles in the project design.Taking into account the fact that the strength check is necessary for the safety of entire towing project,... |
