| 摘 要： | 目前在高速铁路连续梁施工中最常用的施工方法为对称悬臂发浇筑施工，由于桥梁施工分阶段进行，后续梁段的施工将会影响前面已经施工完毕的梁段，改变桥梁的受力与变形，因此，为了保证大桥顺利合龙以及成桥线性美观，成桥后符合设计要求，需要进行必要的线性监控。结合成绵乐铁路跨绕城高速连续梁桥，通过模拟分析施工过程，计算出施工预抬值，并...

| Abstract: | Present continuous beam construction in high-speed railway construction adopts symmetrical cantilever pouring construction often,as bridge construction phases,subsequent beam section in front of the construction will influence the completed beam section has construction,change of the stress and deformation of the bridge,therefore,in order to ensure a smooth closing the bridge and the bridge into the linear appearance,after the bridge met the design requirement,need to undertake necessary linear monitoring.T... |
