穗莞深城际(5×30m)双线变四线道岔连续梁设计与施工

Design and Construction of (5×30m) Double-track to Four-track Line Turnout Continuous Beams in Suiwanshen Interurban Railway

随着高速铁路的发展,桥梁在铁路中所占的比例越来越重,铁路道岔也从路基走上了桥梁,道岔连续梁开始广泛应用。文中以穗莞深城际(5×30m)双线变四线道岔连续梁设计为例,对城际铁路道岔变宽连续梁的设计进行了介绍,阐述了该结构受力特点、计算分析、构造措施及施工方法。

With the development of high-speed railway,more and more bridges appear in the railway construction and the railway turnout also appears in the bridge.The turnout continuous beam is also used widely.Taking the Suiwanshen interurban railway （5×30 m）double-track change to four-track line turnout continuous beam design as an example,this paper introduces the design of widening turn-out continuous beam including the structure characteristics,calculation analysis,structural measures and construction methods.
