移动模架制梁技术在我国桥梁施工中的应用历程

Brief History of MSS Technology Application in China Bridge Construction

我国移动模架制梁技术经历了从国外引进到自主研制的发展历程。国内企业最早于20世纪80年代在建造伊拉克摩苏尔4号桥时从瑞士引进了2套由德国PZ公司设计的移动模架,并于1990年将其改造后用于厦门高集海峡大桥,开启了移动模架在国内的应用历程。文章分析了我国移动模架制梁技术发展过程中的2个不同阶段,归纳了移动模架应用和发展初期的主要工程案例;介绍了移动模架技术在我国高速铁路桥梁建设中发挥的重要作用、专利技术及文献的研究趋势、发展机遇等;针对一些文献中容易将移动模架法和移动支架法相互混淆的情况,阐明了2种工法在技术原理上的重要区别:前者属原位现浇技术,后者属预制架设技术,结合两者在高速铁路桥梁中的应用情况,对其技术特点和各自优势进行了比较,可为相关技术推广研究提供一定的参考。

China＇s MSS technology has gone from abroad to independent research and development process. Domestic en- terprises as early as the 1980s imported 2 sets of MSS designed by German PZ company from Switzerland when the 4th bridge being under construction in Mosul, Iraq. after its renovation in 1990, they were used to Xiamen Gaoqi-Jimei channel Bridge, opened the application process of MSS in China. This paper analyzes China＇s MSS technology development process in two different phases, summarizes the major projects early case of MSS application and development; introduces the important role of MSS technology in high-speed railway bridge construction in China, patent and literature research trends, opportunities, etc. ; against some of the literature is easy to confuse the MSS method and segmental precast erection method, clarifies the important difference of the two methods in technical principles： the former is cast in situ, the latter belongs to precast erection method, combined with the application of two methods in high-speed railway bridges, contrasted the technical features and the respective advantages. These observations provide references for the promotion and research of related technologies.
