预制箱梁节段拼装技术在高铁客运专线应用探讨

Study of the Application of Prefabricated Box Girder Segment Assembly Technique to High-speed Passenger Railway

针对目前预制箱梁节段拼装技术在高速铁路应用不广的现状,结合兰新铁路客运专线现场施工,从技术措施、工期要求、制运架体系造价三个方面,简要分析了预制箱梁节段拼装技术在高速铁路客运专线的应用情况,对预制箱梁节段拼装技术在高铁客运专线的应用前景进行了探讨。

In view of the current status that prefabricated box girder segment assembly technique are not widely applied in high-speed rail, this article makes a brief analysis of the application of prefabricated box girder segment assembly technique to high-speed passenger railway line, and makes a research and study of the application prospects of prefabricated box girder segment assembly technique to high-speed rail passenger railway from three aspects of technical measure, schedule requirements and cost of preeasting-transporting-erecting system.
