摘要
我国在建的最长铁路隧道——秦岭Ⅰ线隧道采用预制钢筋混凝土管片铺设仰拱,这在我国铁路隧道工程中尚属首次。文中详细介绍了秦岭隧道工地混凝土仰拱预制块生产工艺的确定过程及生产试验情况,为今后隧道仰拱预制块的生产提供了第一手资料。
It's the first time for the invert in Qinling No. 1 tunnel, the longest railway tunnel under construction in China, to be installed with prefabricated reinforced concrete elements. This paper introduces in details the determination process of this technology and production as well as test in site, and it can be taken as a reference for future production of prefabricated concrete element for invert in tunnel.
