| 结合广深港客运专线铁路水田特大桥(40+64+40)m高墩连续梁现浇施工,介绍跨路高墩梁柱式支架的设计与施工。该桥梁主墩高31 m,跨越繁忙的石观公路及河流,受地形条件限制,在跨路、跨河处支架采用19.46 m和19.23 m跨径的加强型贝雷梁式支架,贝雷支架上部搭设碗扣支架以满足箱梁变截面要求,下部结构采用钢管支墩、钢筋砼扩大基础,距离河岸边仅3.5 m的扩大基础采用河床堆载反压的方式增强地基承载力,顺利完成了现浇桥梁浇筑,为解决跨路、跨河支架搭设难题积累了经验。 |
| 英文摘要: |
| This paper introduces the design and construction of the beam-column brace spanning road and high-piers based on the construction of cast-in-site continuous beam of Shuitiante bridge in Guangzhou-Shenzhen-Hongkong passenger railway. The main pier of Shuitiante Bridge is 31 meters high and spans the ShiGuan road and a river. Constrained by the geomorphology, the reinforced bailey trusses are adopted with the spans of 19.46 m and 19.23 m for road and river respectively. The bowl scaffold is built on the bailey truss to meet the needs of the mould of variable section bridge beam and the tube truss brace composing the substructure is used to spread foundation. The spread foundation which is 3.5 meters away from river bank is reinforced by the counter pressure on the riverbed. And the bridge beam is cast successfully with the above measures and the experience is drawn for the building of brace spanning road and river. |
