摘要
在京沪高速铁路高架车站道岔区桥梁设计中,考虑了道岔与桥梁的相互作用,道岔梁采用连续梁,较好地控制了道岔距梁缝的距离,在渡线两联连续梁之间插入两孔及简支梁,适当地提高了道岔梁及桥墩的刚度。通过以上措施,道岔区桥梁、轨道,道岔的强度、稳定、位移均能满足规范要求;车速350km/h的高速列车通过道岔区时,"车-岔-桥"动力性能满足规范要求。
In the design for bridges of turnout area in elevated stations in Beijing-Shanghai high-speed railway, the interaction between turnouts and bridges was taken into account, continuous beams was applied to controlling the distance between the end of beams and turnout. Designers inserted at least two simply supported beams between two continuous beams, appropriately improved the stiffness of beams and piers in Turnout Area. By taking these measures, all the strength, stability, displacement of bridges and tracks and turnouts can meet the requirements of the codes. When the vehicles pass through turnout area at the speed of 350 km/h, the dynamic performance of vehicle-turnout-bridge can meet the requirements of the codes.
