项目摘要
The Chousei bridge and the Taihei bridge are the first prestressed concrete bridges (PC) in Japan, which were constructed in 1953 and 1954 across the Misogi river in Nanao city in Ishikawa Prefecture. After symbolizing the birth of PC bridge in Japan for 50 years, the bridge was earmarked for relocation as part of an urban development project. They were dismantled in August 2000 and in September 2001. Following its removal, some of the girders were subjected to examination and load testing to determine both the physical and chemical properties of old concrete and the load-bearing capacity of old bridge. The water to cement ratio of the concrete was found to be as low as 33 % and it texture was also very dense. This proves that the concrete mixed for bridge is very durable, which results in no carbonation of concrete and little corrosion of stee bars and PC wires in concrete. The bending and shearing load capacity of girders of the gbridge was also found to be satisfactory for the requirements of specifications of road bridges. After the test, the Chousei bridge was relocated to the memorial park on the outskirts of Nanao city.
Chousei大桥和太平大桥是日本第一座预应力混凝土桥梁(PC),分别于1953年和1954年在石川县南澳市的米佐木河上修建。在象征着PC桥在日本诞生50年后,这座桥被指定用于搬迁,作为城市发展项目的一部分。它们分别于2000年8月和2001年9月被拆除。拆除后,对部分梁进行了检测和荷载试验,以确定旧混凝土的物理和化学性质以及旧桥的承载能力。混凝土的水灰比低至33%,质地也非常致密。结果表明,桥梁混凝土具有良好的耐久性,混凝土不会发生碳化,混凝土中钢筋和PC钢丝的锈蚀程度较小。桥梁主梁的抗弯和抗剪承载能力也满足公路桥梁规范的要求。测试结束后,Chousei大桥被搬迁到南澳市郊的纪念公园。
