随着我国经济的发展,很多地区对高架桥的需求增加,推动了桥梁事业的发展,在桥梁建设过程中,大跨度预应力混凝土连续箱梁施工技术得到了应用和发展。和国外的技术相比虽然还存在一定的差距,但是在不断的实践总结中该技术不断改进成熟,主要涉及到支架操作,大体积混凝土施工,箱梁预应力施工等。下面就对这些方面进行分析,希望给有关人士一些借鉴。 With the economic development in our country, the demand for viaducts in many areas has increased, which has promoted the development of the bridge. During the process of bridge construction, the construction technology of long-span prestressed concrete continuous box girders has been applied and developed. Compared with foreign technology, although there is still a certain gap, but in constant practice summary of the technology continues to improve and mature, mainly related to the stent operation, mass concrete construction, prestressed box girder construction. The following analysis of these aspects, I hope to give some reference to the people concerned.
