【摘要】：晋中南重载铁路与京沪高铁在山东泰安地区交叉,其上跨京沪高速铁路方案存在影响高速铁路运营安全的风险,而下穿京沪高速铁路方案,其线路在交叉处北临大汶河,设计的路肩高程低于大汶河百年洪水位。如何使晋中南铁路设计既满足铁路防洪要求,又避免重载列车运营时的动应力对高速铁路桥墩产生不利影响,是两线立交方案需要研究解决的关键问题。研究提出采用路堤式U形槽下穿京沪高速铁路的方案,解决了上述关键技术问题,使得方案顺利通过技术审查并实施,取得了良好的设计效果。
[Abstract]:The Jinzhong South heavy haul Railway and the Beijing-Shanghai High Speed Railway cross each other in the Taian area of Shandong Province. The plan for the upper trans-Beijing-Shanghai high-speed railway has the risk of affecting the operational safety of the high-speed railway, while the route below the Beijing-Shanghai high-speed railway scheme is located at the crossing point near the Davin River to the north.The designed shoulder elevation is lower than the century flood level of the Davin River.How to make the design of Jinzhong South Railway not only meet the requirements of railway flood control, but also avoid the adverse impact of dynamic stress on the bridge piers of high-speed railway during the operation of heavy-haul trains, is the key problem that needs to be studied and solved in the scheme of two-line interchange.This paper puts forward the scheme of using the embankment U-groove to cross the Beijing-Shanghai high-speed railway, which solves the key technical problems mentioned above, and makes the scheme pass through the technical examination and implement smoothly, and obtains good design effect.
