钢管混凝土拱桥局部拆除施工方案

Partial Demolition Construction Scheme of Concrete-filled Steel Tubular Arch Bridge

文章结合济青高速K15+709跨线桥的拆除施工,对中承式钢管混凝土拱桥的拆除过程中的施工难点进行研究,并提供解决措施。根据济青高速K15+709跨线桥自身拆除要求、受力特点及环境限制,初步确定了拆除方案,主要包括工程概况、拆除工程范围、工程难点及采取的措施等,对同类桥梁的拆除施工具有一定的参考价值。

This paper combines the demolition of the K15+709 overpass bridge of Jiqing Expressway to study the construction difficulties in the process of dismantling the medium-concrete-filled steel tubes arch bridge and provide solutions.According to the demolition requirements,force characteristics and environmental constraints of the K15+709 overpass bridge of Jiqing Expressway,the demolition plan was initially determined,including the project overview,the scope of the demolition project,the engineering difficulties and the measures taken,etc.,which had a certain reference value for the demolition of similar bridges.
