摘　　要：北京轨道交通房山线区间桥梁工程在丰西铁路编组站区域内需4次跨越铁路,详细介绍了采用水平转体施工技术的4座桥梁设计、施工要点及技术关键,并在总结回顾的基础上,分析了目前我国水平转体技术桥梁设计施工受到的制约因素,为今后在跨越高速公路、铁路、河流等桥梁设计提供参考。Beijing Rail Transit Fangshan Line shall cross the railway four times in the Fengxi marshalling yard,thus,there four bridges were constructed by horizontal rotation construction technology.It describes the main points of horizontal rotation technology,and analyzes the technical constraints on the design and construction of such a bridge in China on the basis of reviewing the technology development,and proposes the ideas on how to improve the processing techniques of ball-hinge,which will provide the reference for the similar bridges over expressway,railway and river.
