Design of A Movable Automobile Trestle Bridge for Guangdong-Hainan Island Railway Link

粤海铁路通道是我国第一条跨海铁路,通过粤海一号渡轮将火车及汽车渡过琼洲海峡,在南北两岸港口设火车及汽车活动栈桥将渡轮与陆地相连,栈桥前端搭于渡轮甲板,因此其前端高程必须可调节以适应潮差的影响,其结构设计及细节处理与普通桥梁有很大不同。在此主要对汽车活动栈桥的设计特点作扼要介绍。

The GuangdongHainan Island Railway Link is the first railway line stretching across the straits (Qiongzhou Straits between Guangdong and Hainan Island) in China, where the trains and automobiles are transported across the Straits by Ferry Yuehai No.1. At the ports on the south and north banks, the movable train and automobile trestle bridges will be built, connecting the ferry to the land. Because the front parts of the trestles will be set on deck of the ferry, they must be adaptable to the tidal variations, and the structural design and details of the bridges are thus much different from those of the normal bridges. In this paper, the design features of a movable automobile trestle bridge are presented.
