摘要
赵家沟大桥为轨道交通六号线和浦兴路道路交通合建桥梁,是目前上海轨道交通跨度最大的公铁合一的钢筋混凝土预应力拱桥,主桥跨度88 m,全桥长441.29 m。桥梁基础采用钻孔灌注桩和PHC管桩,下部结构为承台、立柱、盖梁,引桥上部结构为后张预应力混凝土箱梁,主桥上部结构为一孔下承式预应力钢筋混凝土简支四榀系杆拱。文中主要介绍赵家沟大桥工程概况、设计施工方案、监理质量控制点和针对性措施、桥梁检测技术等,还对钢筋混凝土预应力拱桥的施工监理技术要点难点进行了分析和研究。
The Zhaojiagou bridge for No. 6 rail transit and Puxin road is the biggest span pre-stressed concrete arched bridge. Bridge foundation is the drill hole pile and the PHC pile, the substructure is the base column and the beam, the approach span superstructure is post tension prestressed concrete box beam, the main span superstructure is prestressed concrete for supported four-pin tied arch bridge. All of the issures related to project survey, design and construction plan, quality control point and measure, bridge inspection for pre- stressed concrete arched bridge were studied in this paper, which can offer reference to similar engineering.
