摘　　要：冬季,我国辽东湾及其鲅鱼圈海域都被海冰所覆盖。在布满流冰的海面上,电厂主机循环冷却水取水口畅通是保障电厂正常运行的关键所在。该工程是我国目前唯一的在结冰海域自然环境里取水的工程。为准确详细地分析取水口工程构筑物与海冰的相互作用,流冰在取水前池的生成、发展分布及运动等,特别是重冰年对取水的影响。针对不同水位、模拟计算分析隧洞取水前池的冰冻情况对取水的影响。本文的研究和分析方法及成果,为今后解决在结冰海域建设冰覆盖下取水工程技术措施提供借鉴。The Liaodong Bay and the waters near Bayuquan are coverd by sea ice in the winter. A key problem of maintaining regural operation of the power plant is to make the cycle cooling water flow without a hitch through the water intake engineering in the sea ice covered waters. The engineering is a unique water intake engineering located at the sea ice covered waters in our country. In this paper, the ice / structure interaction, the generation, growth and distribution and movement of pack ice in the water supply front pool, especially the effect of severe ice year on the supply water process, were exactly and clearly analysed. And the effect of sea ice condition on the water supply process was calculated in different water levels.The method of simulation and analysis and the achievement in this paper provide a reference for adopting technical measure of building other water intake in the sea ice covered waters in the future.
