摘要
现浇预应力混凝土箱梁是最近几年在铁路、公路和城市道路中最为常见的上部结构形式之一,其施工质量对整体结构至关重要.结合某立交桥现浇预应力混凝土连续箱梁具体实践,对现浇预应力混凝土连续箱梁的关键施工技术进行了论述,给出了各关键施工工序的具体处理措施,为现浇预应力混凝土箱梁的施工提供技术参考.
The pre-stressed reinforced concrete box girder has been one of the most common structures on the railways,highways and urban roads in recent years,and the quality of construction directly affects the overall structure. Based on the construction practice of the pre-stressed reinforced concrete box girder of an overpass, the key construction technologies of the pre-stressed reinforced concrete box girder are discussed,the specific measures of key construction process and technical reference for the construction of pre-stressed reinforced concrete box girder are put forward.
