本文综述了我国混凝土桥梁主要的架设方法,即梁桥的悬拼和悬浇法;拱桥的缆索吊装法、桁架伸臂法、埋入式拱架法、转体法;顶推法;移动支架法;斜张桥以及中小桥的架设方法。回顾了我国桥梁架设方法的发展,叙述了架设方法的现状,展望了架设方法的前景,特别对我国独创的拱桥平转法给予了很高评价。笔者认为:1.一种架设方法是否有发展前途和生命力,要看它是否结合我国实际情况;要看施工用料及临时设施是否少而省。2.选用架设方法时要因地制宜,灵活采用。3.努力独创一些自己的架设技术和方法,赶超世界先进水平。
In this paper, the main erection methods of concrete bridges in our country are summarized, such as cantilever method and overcasting method of girder bridge, cable hoisting method of arch bridge, truss boom method, buried arch method, swivel method, push method, mobile bracket Method; diagonal tension bridge and small bridge erection method. The development of bridge erection method in our country is reviewed. The current situation of erection method is described. The prospect of erection method is forecasted. Especially, the original translation method of arch bridge in our country is given a high evaluation. The author thinks: 1. Whether a method of erection has development prospects and vitality depends on whether it is combined with the actual situation in our country; it depends on whether the materials for construction and the temporary facilities are few and the province. 2. Choose erection method should be adapted to local conditions, flexible use. 3. Strive to create some of their own erection technologies and methods to catch up with the advanced world level.
