1988年10月2日至23日,由交通部公路科学研究所和交通部重庆公路科学研究所组成的交通部桥梁工程考察团,应日本国(株)会津工建社梅木信秋社长的邀请,对日本福岛县的桥梁和道路等工程进行了考察。其间对横向1号桥进行了为期1O天的考察,经历了一个完整的顶推施工周期,详细地了解了小半径混凝土连续弯箱梁桥的顶推施工技术,考察期间举行了7次技术座谈会,收第了日本高速公路、桥梁、隧道等有关资料。现把横向1号桥——顶推法施工的弯桥介绍如下,供同行参考。
From October 2 to October 23, 1988, a bridge engineering study group of the Ministry of Communications, composed of the Highway Science Research Institute of the Ministry of Communications and the Chongqing Highway Science Research Institute of the Ministry of Communications, was invited by Japan’s President Aimin Construction Co., Ltd. Invitations, the bridge and roads in Fukushima Prefecture, Japan conducted a study. In the meantime, the 1-day inspection of horizontal No.1 bridge was underway. After a complete push-push construction cycle, a detailed understanding of the technology of jacking construction of small radius concrete continuous curved box girder bridge was held. During the inspection, seven technical discussions were held Will receive the Japanese highway, bridges, tunnels and other related information. The horizontal is now No. 1 Bridge - push the construction of curved bridge introduced below, for peer reference.
