摘要
为了提高铁路轮渡系统的通用性和兼容性,提出一种新型折线型活动栈桥设计方案。根据轮渡系统中柔性轨道的需要,从几何构造的角度,分析活动栈桥的基本构造和工作机理,探讨桥跨数目对其他相关参数的影响,并推导出了桥体长度、桥面宽度及柔性可动段的横梁间隙等相关参数的表达式,为活动栈桥的方案设计提供了参考。
To improve the efficiency and compatibility of the train ferry system, a turning joint type movable trestle bridge design is proposed. According to the needs of flexible railway and from the perspective of geometric construction, analyses of the basic structure and working mechanism of the movable bridge were carried out to study the influence of the number of spans on other parameters, and the expression for span length, bridge width, spacing of the crossbeams and other related parameters was deducted, providing basis for the further design of movable trestle bridges.
