一、工程中提出的问题由于在寒冷海域进行的海洋工程活动日益增多,其中因考虑经济、使用等方面因素,常选用柔度较高的结构,因而出现一种由海冰引起的特殊的结构振动现象。它的破坏作用十分显著。国内、外已有一些由此而造成的结构失事的先例,因而正引起海洋工程结构工作者的注意。
I. PROBLEMS PROJECTED IN PROJECTS Because of the increasing number of marine engineering activities in the cold waters, a special structure due to sea ice appears due to the fact that the structures with higher flexibility are often chosen due to factors such as economy and use. Vibration phenomenon. Its destructive effect is very significant. There have been a number of domestic and foreign precedents of structural calamities that are causing the attention of workers in offshore structures.
