我国海冰的可能最大厚度

POSSIBLE MAXIMUM ICE THICKNESS IN CHINA

我国的渤海和黄海北部近岸海域,每年冬季都有海冰出现,渤海的辽东湾是我国冰情最严重的海区。在渤海,特别是在辽东湾,海冰作用力是海洋工程设计的控制荷载。 海冰的厚度是计算海冰作用力的重要参数之一。本文根据渤海辽东湾北部鲅鱼圈和盘锦海洋站的气温和海冰观测资料,建立了计算海冰厚度的经验公式,并据此估算了我国平整海冰的可能最大厚度为80cm。

In the coastal waters of the Bohai Sea and the northern part of the Yellow Sea, sea ice occurs at each winter, with the Liaodong Bay of the Bohai Sea being the heaviest icing area in China. In the Bohai Sea, especially in the Liaodong Bay, sea ice force is the controlling load in marine engineering design. Sea ice thickness is one of the important parameters involved in the evaluation of sea ice force. Based on the air temperature and sea ice observations taken at Bayuquan and Panjin marine observatories located in the North Liaodong Bay, an empirical formula for determination of the ice thickness was established, after which, the maximum thickness of level sea ice possible in China was estimated to be 80 cm.
