摘　　要：研究目的:近年来,随着各种连续梁和简支梁桥修建的增多,如何快速化、标准化、经济地施工这类桥梁显得尤为重要。本架桥机以桃花峪黄河大桥北引桥为工程依托,研究采用拼装式架桥机进行节段施工拼装的施工方法,以保证施工工期以及节省成本。研究结论:通过对拼装式架桥机的结构进行建模分析,结果表明:(1)该架桥机的结构完全可以满足施工的要求,刚度比制式架桥机大约1.5倍;(2)由于该架桥机最大限度地利用了常备式杆件,大大减少了新制杆件的投入,节省成本达50%;(3)该架桥机采用了滑板走行的方式,走行平顺,操纵方便,安全可靠;(4)通过对架桥机结构设计及施工流程的分析和论述,可为今后同类型架桥机的设计提供借鉴。Research purposes： In recent years, with increase of construction of a variety of continuous beam and simply supported beam bridges, how to quickly, standardizedly and economically construct such kind of the bridges becomes the very important. Taking the bridge erecting machine used for the north bridge approach of the Taohuayu Yellow River bridge as an example, the study was done on the construction method for segmental assembling construction by using the assembled bridging machine in order to ensure the construction schedule and save the construction cost. Research conclusions：The model was established to analyze the structure of the assembled bridge erecting machine. The analysis results showed that the structure of the bridge erecting machine could meet the construction requirements, and its stiffness was stronger than standard bridge erecting machine by about 1.5 times. With full use of the existing member bars for the this bridge erecting machine, the investment in manufacturing new kind of member bars was much reduced and the cost was saved by 50%. The bridge erecting machine runs on the slide board with the features of smooth running, easy operation, safety and reliability. It can provide the reference to similar works.
