摘要
建立了道岔-桥梁-墩台一体化计算模型。以60kg/m钢轨12号可动心轨道岔为例,分析了在长大连续梁桥上铺设有无缝道岔及伸缩调节器时,墩台及钢轨的受力与变形规律,探讨了无缝道岔布置方式、与伸缩调节器的距离等因素的影响,为桥上无缝道岔设计提供了理论依据。
An integral calculation model of seamless turnout-beam-pier was established. Taking size 12 swing nose turnout by 60 kg/m rail as an example, the expansion joint was installed on large continuous beam, the stress and distortion rule of pier and rail are analyzed. The factors, such as, setting style of seamless turnout, the distance of the expansion joint, and so on, are also discussed. So, a theoretic base for design of seamless turnout on bridge is offered.
