摘　　要：高架预制节段梁施工涉及多个环节,每一个环节的质量都会影响高架桥整体性能。文章基于短线匹配法的高架预制节段梁预制质量控制,应用短线匹配法控制预制节段梁梁体线形匹配质量,优化英标混凝土配合比设计,控制英标混凝土温度,精细化施工管理,定制不锈钢模优化拆模设计等方法实现英标预制节段梁的质量控制。综合应用上述技术措施和控制方法,不仅能提高预制节段梁的质量和性能,还能满足国际标准和市场需求,提升我国桥梁建设的国际竞争力。Elevated prefabricated segmental beam construction involves many links,and the quality of each link will affect the overall performance of the viaduct.Based on the prefabrication quality control of the elevated prefabricated segmental beam by the short-line matching method,this paper applies the short-line matching method to control the linear matching quality of the prefabricated segmental beam,optimize the mixture proportion design of the concrete with British standard,control the temperature of the concrete with British standard,refi ne the construction management,and customize the stainless steel mold to optimize the formwork removal design and other methods to achieve the quality control of the prefabricated segmental beams with British standard.The comprehensive application of the above technical measures and control methods can not only improve the quality and performance of prefabricated segmental beams,but also meet the international standards and market demand,and enhance the international competitiveness of China's bridge construction.
