【摘要】：晉中南重載鐵路與京滬高鐵在山東泰安地區(qū)交叉,其上跨京滬高速鐵路方案存在影響高速鐵路運(yùn)營安全的風(fēng)險(xiǎn),而下穿京滬高速鐵路方案,其線路在交叉處北臨大汶河,設(shè)計(jì)的路肩高程低于大汶河百年洪水位。如何使晉中南鐵路設(shè)計(jì)既滿足鐵路防洪要求,又避免重載列車運(yùn)營時(shí)的動(dòng)應(yīng)力對高速鐵路橋墩產(chǎn)生不利影響,是兩線立交方案需要研究解決的關(guān)鍵問題。研究提出采用路堤式U形槽下穿京滬高速鐵路的方案,解決了上述關(guān)鍵技術(shù)問題,使得方案順利通過技術(shù)審查并實(shí)施,取得了良好的設(shè)計(jì)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.
