摘　　要：预制节段梁作为城市高架道路交通的现浇桥梁替代,在国内各大城市的应用已愈加广泛,工厂化预制、现场拼装已成为城市立交、快速路桥梁建设的首选,具有场外预制、施工快速简洁、城市环境污染低等优点。但受限于城市交通环境的复杂性,节段梁的现场拼装方案需要因地制宜。本文结合工程项目实际施工中遇到的各种情况,对节段梁拼装方案的选择及应用进行分析,从而为后续其他同类工程的节段梁拼装施工提供经验和支持。Precast segment,as cast-in-place Bridges for urban viaduct traffic,have been widely used in major cities in China.Factory precast and site assembly have become the first choice for urban interchange and expressway bridge construction,with advantages of off-site precast,quick and simple construction and low urban environmental pollution.However,due to the complexity of urban traffic environment,the site assembly method of segment needs to adapt to local conditions.This article analyzes the selection and application of segment assembly method based on various situations encountered in the actual construction of the project,so as to provide experience and support for the subsequent segment assembly construction of other similar projects.
