Discussion on Cantilever to Cast-in-situ scheme of Continuous Beam of a Bridge(60+100+60) m on Harbin-Tsitsihar Passenger Dedicated Line for

以哈尔滨至齐齐哈尔铁路客运专线跨化工厂专用线特大桥连续梁(60+100+60)m工程为实例,从单位工程施工进度、方案可行性、施工成本控制等方面对连续梁挂篮悬灌和支架现浇施工方案进行对比,探讨铁路客运专线大跨度连续梁悬灌改现浇施工方案的可行性,浅述支架现浇设计方案。

Referring to the project of the continuous beam （60 ＋ 100 ＋ 60） m over a chemical plant on Harbin to Qiqihar Railway Passenger Dedicated Line, the study compares the continuous beam hanging basket irrigation and support cast-in- place construction scheme from the unit project construction progress, program feasibility, construction cost control and oth- er aspects, explores the feasibility of cantilever to cast-in-situ large span continuous beam of railway passenger, and makes a brief discussion on the bracket cast design.
