波形钢腹板组合梁桥异步平行法的实践应用

Practical application of asynchronous parallel algorithm for composite beam bridge of corrugated steel web

以某高速公路黄河大桥波形钢腹板刚构—连续组合梁桥施工为例,针对波形钢腹板特点进行了深入分析,提出了适用于波形钢腹板组合梁桥施工的异部平行施工方法,并深入阐述了施工方法的特点、工艺原理、流程及操作要点、材料与设备和质量控制等内容,同时通过施工方法的实践运用,安全、保质、高效地完成了桥梁主体结构的施工,取得了良好的社会效益和经济效益。

Taking the rigid-continuous composite bridge construction of corrugated steel web of the high way Yellow River as an example, the paperanalyzes characteristics of corrugated steel web, puts forward asynchronous parallel construction methods of composite beam bridge construction ofcorrugated steel web, illustrates construction method features, construction technology principles, procedures and operation points, material andequipment and quality control and so on. Through the practical application of consruction method, it accomplishes safe high-effecient and highquality construction of the major bridge structure and achieves great social and economic benefits as well.
