铁路T构连续梁转体桥施工关键技术

Key Technology for the Construction of Railway T-structure Continuous Beam Transfer Bridge

本文基于阳大铁路桃河大桥上跨铁路2×56mT构连续梁转体桥施工实践,对转体转动系统球绞与滑道精确定位技术,T构连续梁转体桥线形及内应力控制技术,转体不平衡力测试称重及配重技术,转体水平转动牵引技术等关键工程技术实践的应用,为今后类似工程提供借鉴与参考。

Based on the construction practice of 256mT continuous beam transfer bridge,the application of key engineering techniques of ball ring and slide,linear shape and internal stress control technology,weighing and weighing technology,and provide reference for similar engineering in the future project.
