高铁站站前广场高架桥钢箱梁架设支撑体系设计

Design of Support System for Erection of Seel Box Girder of Viaduct on High Speed Rail Station Square

高架桥被越来越多地用于高铁车站与站外道路的联络线。因其一般为曲线形式,其钢箱梁架设不仅要受到线形控制,还须考虑车站建筑的限制,使架设难度加大。以某市高铁站站前广场高架桥工程项目为依托,考虑到该工程特点,采用钢管柱墩与梁组合来搭设钢箱梁架设用的临时支撑体系,并简单介绍了该支撑体系的布置形式和设计过程,不仅为该工程的成功建设提供了技术指导,也为今后类似工程提供了参考。

The viaduct is more and more used in the tie line between high-speed railway station and out of the way road. Because of the general curve form, the erection of steel box girder is not only subjected to linear control, but also must consider the station building restrictions, so the erection is difficult. Taking a high-speed rail station square viaduct project, considering the features of the project,temporary support system is to use steel pipe column pier and beam to erect steel box girder, and this paper briefly introduces the layout form and design process of this support system, which not only provides technical guidance for the successful construction of the project, but also provide a reference for similar projects in the future.
