某线跨度150m钢筋混凝土拱桥于1966年建成,通车后使用情况良好。为了正确掌握桥梁技术状态,总结经验,根据交通部指示,于1972年对拱桥进行了检定试验。试验由检定、设计、科研和使用等单位共同组成。参加单位有:北京、郑州、济南铁路局,交通部科学研究院,中国科学院工程力学研究所,第三铁路设计院。试验工作自1972年8月8日开始至9月22
A span of 150m reinforced concrete arch bridge was completed in 1966, opened to traffic in good condition. In order to correctly grasp the technical status of the bridge, summarize the experience, according to the instructions of the Ministry of Communications, in 1972 the arch bridge was tested. Test by the test, design, research and use of other units together. Participating units are: Beijing, Zhengzhou, Jinan Railway Bureau, Ministry of Science and Research Institute of Transportation, Institute of Engineering Mechanics, Chinese Academy of Sciences, the Third Railway Design Institute. Experimental work from August 8, 1972 until September 22
