杭州东站站房工程跨涵沟贝雷桥设计与施工

Design and Construction of Crossing Trench Bailey Bridge of Newly-built Hangzhou East Railway Station

杭州东站枢纽工程是由多个功能主体、多家建设与施工单位交界、交叉施工的大型综合枢纽工程,特别是站房工程作为枢纽工程核心,处于南北站场、东西站前广场的包围之中,建设环境非常复杂。在结构施工后期与装饰施工阶段,由于南北站场、诸多跨线涵沟等的施工,进入站房临时道路需要逐步迁移或变更,而在涵沟位置,因为贝雷桥具有搭拆便捷、稳定性好与负载高等特点,被广泛采用,结合工程实际,对贝雷桥设计、施工进行总结。

Newly-buih Hangzhou East Railway Station is a large-scale comprehensive hub, which comprises many function subjects （station building, station yard, station circus）, many construction and building units that have a common border, and be constructed with intersection. Particularly, as the core project, the project of station building is surrounded by north, south, east and west square, of which the construction environment is very complicated. In the later period of structure construction and the period of decoration, the temporary channel of entering station building needs to be gradually moved or changed due to the construction of north and south station yards and of many line-crossing trench and of others. However, Bailey bridge was extensively adopted for its convenience of erection and demolition, good stability, high load capacity and other features in the place of trench. This paper summarized the design and construction of Bailey bridge combined with the practice of project.
