摘要
为在海洋环境中选择合适的承台形式,以东海大桥为工程背景,依据中国、英国和美国的规范,比较了不同形状承台在波浪力、水流力和波流合力作用下的受力特点,分析了这些荷载的作用效应,根据不同的方向波和流力作用,提出了选择合理承台形式的思路,并根据东海大桥所处海洋环境,选择了波流作用影响最小的承台形式。
For the appropriate form of pile cap in marine environment,according to Chinese,English and American standards,the different forms of pile caps＇ mechanical characteristics and action effects by wave force and water current force and their interaction are compared and analyzed with the background of the Donghai Bridge.Due to the different direction waves and current forces,a reasonable approach is put forward to select the pile cap form.Considering to the marine environment of the Donghai Bridge the pile cap was chosen by the minimal impact.
