摘　　要：以高速铁路大跨度拱加劲连续梁工程为依托,加劲钢管拱利用桥位边跨整体拼装顶推技术,工艺安全可靠,经济效益明显,可为类似钢管拱工程提供借鉴。Relying on the high-speed railway long-span stiffened continuous beam project,the stiffened steel tube arch utilizes the integral assembly and thrusting technology of the side span of the bridge location.The process is safe and reliable,and the economic benefits are obvious.It can provide reference for similar steel tube arch projects.

关 键 词：高速铁路 拱加劲连续梁 钢管拱 顶推工艺
