大型浮箱式坞门工作状态下的横稳性分析

用于现代修造船坞的钢质浮箱式坞门从早期的小型趋向大型、超大型。为了更好地进行浮箱式坞门的设计工作，根据浮箱式坞门的工作原理、结构形式和沉浮过程，结合实例分析，针对大型浮箱式坞门工作状态下的横稳心高度变化趋势进行总结，给出了横稳心高度变化的一般规律，发现坞门沉浮过程中横稳心高度的突变点及最危险的时刻，最后提出设计优化措施。

Analysis of transverse stability of large floating caisson under working condition

The steel floating caisson used in modern ship building and repairing tends to be large and ultra-large. In the design of the floating caisson, this paper describes the general variation law of the transverse meta-centric height according to the working principle, structural type and up-down process and in combination with the real case analysis, finds out the abrupt variation point and the most dangerous moment of the transverse metacentric height in the up-down process of the dock wall, and proposes the optimization measures of design.
