沧德特大桥跨京沪铁路既有线连续梁转体施工安全管理

Safety Management of Continuous Beam Swivel Construction of Cangde Grand Bridge Crossing Beijing-Shanghai Railway Existing Lines

京沪高速铁路是我国一次建成线路最长、标准最高、速度最快的世界级高速铁路。京沪铁路连接着我国政治、文化中心城市北京和经济中心城市上海,列车运行密度大,时间间隔短,申请天窗施工非常困难。京沪高铁跨京沪铁路转体施工既可以减少既有线施工要点的次数,加快施工的速度,又可以降低既有线施工的安全风险。

Beijing-Shanghai high-speed railway is the world-class high-speed railway which has the longest line,the highest standard and the fastest speed in our country.Beijing-Shanghai railway links Beijing,our country＇s political and cultural center and Shanghai,our country＇s economic center.Due to the high density of train operation and short time interval,it is difficult to apply for roof construction in the present railway.The swivel construction of Beijing-Shanghai high-speed railway crossing Beijing-Shanghai railway can reduce construction points of existing railway,accelerate the construction speed,and also reduce the security risk of existing line construction.
