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, the proportion of bridges in the railway is more and more heavy, railway turnouts also embarked on the bridge from the roadbed, continuous beam turnout began to be widely used. Taking the design of continuous beam of double-line four-switch turnout in Suiwan-Shenzhen inter-city (5 × 30m) as an example, the design of widened continuous beam of intercity railroad turnout is introduced. The stress characteristics, calculation and analysis of the structure, Construction measures and construction methods.
