建造海上工程船舶 实现从长江内河向海上建桥的跨越

Building Marine Engineering Vessels and Realizing a Leap of Bridge Construction from Inland Changjiang River to Sea

上海东海大桥和杭州湾大桥成为我国海上大桥建设真正意义上的开始,以这两桥建设为契机,中铁大桥局实现了从长江内河向海上建桥的跨越,开始了海上工程船舶设备的装备发展过程,其中包括"小天鹅"号运架梁起重船、"天一号"运架梁起重船等。介绍各工程船舶的主要技术特点和性能。

The construction of Donghai Bridge in Shanghai and Hangzhou Bay Bridge is in the real sense the outset of bridge construction at sea in China. Along with the construction of these two bridges, China Zhongtie Major Bridge Engineering Group has realized a leap of bridge construction from inland Changjiang River to sea, and therefore started a journey of development of the equipment for marine engineering vessels, including those of the ＂Little Swan＂ and ＂Tianyi＂ lifting vessels for both girder transportation and erection. In this paper, the principal technical features and performance of different types of the marine engineering vessels are dealt with.
