摘　　要：通过实际工程中新建铁路与既有规划铁路、道路、管道立交复杂区域桥涵选型与布设及结构设计的实例,阐述了双单线桥梁错孔布置、异形框构、小跨度梁与框架墩结合等立体交叉形式的适应性及特点;提出了采用中、小跨度结构、异形结构跨越既有结构物的设计思路,为铁路工程及涉铁工程解决立交穿(跨)越问题提供桥跨布置、线桥协同设计参考。This article elaborates on the adaptability and characteristics of the three-dimensional intersection forms of double single track bridges,such as staggered layout,irregular frame structure,and the combination of small span beams and frame piers,through examples of bridge and culvert selection,layout,and structural design in complex areas of newly-built railways and existing and planned railways,roads,and pipeline overpasses in practical engineering;the design concept of using medium and small span structures and irregular structures to cross existing structures has been proposed,providing reference for bridge span layout and line bridge collaborative design for railway engineering and railway related engineering to solve the problem of overpass crossing.
