深海珊瑚礁地质建设条件下大桥设计方案

Design Scheme of Bridges with the Geological Construction Conditions of Deep-sea Coral Reef

中马友谊大桥连接马尔代夫首都马累和机场岛,最大水深达46 m,且为珊瑚礁地质,波浪周期长,处于高温、高湿和高盐度极端腐蚀环境,航空限高严苛。针对上述特殊的建设条件,阐述了各项有针对性的设计方案,解决上述难题,并成功实施,为今后的跨海桥梁设计提供参考和经验。

The China-Maldives Friendship Bridge connects Male’, the capital of Maldives, and the airport island,with the maximum water depth of 46m,where is featured with coral reef geology,long wave period,extremely corrosive environment of high temperature,high humidity and high salinity,and strict aviation height limit.In view of the above special construction conditions,several specific design schemes are introduced in the paper so as to solve the above complicated physical construction problems.The solutions are executed successfully,so as to provide reference and experience for the design of seacrossing bridges in the future.
