摘　　要：海洋平台作为集生产、生活、国防于一体的多功能海上设施,在外部作用下极易引发局部火灾、爆炸,进而造成严重的人员、财产损失。为研究非均匀温度场和波浪荷载耦合作用下海洋平台房间的结构热响应,本文基于FDS和ABAQUS,以某特定房间为例,研究其燃烧因素对房间温度场的影响。利用自建的火灾-热-结构耦合数据,研究房间火灾下的应力演变规律。结果显示:房间尺寸大的房间火源燃烧更为充分且高温区域更大;火源的热释放速率与火灾稳定后房间内的平均温度成正相关。此外,外部波浪载荷对火灾下房间应变的影响主要由其幅值和圆频率决定。As a multi-functional offshore facility integrating production, life and national defense, offshore platform is easy to cause local fire and explosion under external action, resulting in serious personnel and property losses. In order to study the structural thermal response of the offshore platform room under the coupling effect of non-uniform temperature field and wave load, based on FDS and ABAQUS, this paper takes a specific room as an example to study the influence of combustion factors on the temperature field of the room. Using self-built fire-thermal-structure coupling data, the stress evolution law under room fire is studied. The results show that the room with large room size burns more fully and has a larger high temperature area. The heat release rate of the fire source is positively correlated with the average temperature in the room after the fire is stable. In addition, the influence of external wave load on the strain of the room under fire is mainly determined by its amplitude and circular frequency.
