摘　　要：为提高铁路轮渡栈桥对船型的适应性，提出一种一端固定连接岸上，另一端能够上下、左右移动，从而连接来船不同部位，便于车辆进出船舱的柔性或活动船岸连接栈桥构造方案。给出这种新型柔性栈桥的基本构造和主要构件组装特征，说明了其工作原理。进而推导出栈桥活动端的横移距离、偏转角度、纵桁外伸长度等关键设计参数的函数关系。研究结果表明，这种新型柔性栈桥具有可行性和实用性。To enhance the applicability of the trestle bridge for train ferries, a novel flexible linkspan is put forward which can be hinged to shore at one end and moved up and down and also left and right at the other end, and hence can be connected to various decks on board to facilitate the loading or discharging of rolling stock. The basic configuration of the flexible linkspan and the assembling feature of its main parts are presented with a description of its working mechanism. The key parameters of the flexible linkspan, such as transverse moving distance of the moving end, turning angle of the linkspan, overhang length of earlings, are also formulated. The initial research outcomes show that the new type of flexible linkspan is feasible and practical.
