根据国家的计划,九江长江大桥即将继续施工,要求在1990年第一季度公路通车,因此钢梁的设计任务非常紧急。九江桥是采用国产15MnVNq钢制造,在现行铁路桥梁规程中没有15MnVNq钢的设计参数,为此,铁道部大桥工程局,勘测设计院总结了过去的试验资料,综合了国内外可参考的研究成果,提出了“九江长江大桥15MnVNq钢压杆设计规则条文和说明(讨论稿)”和“九江长江大桥15MnVNq钢高强度螺
According to the national plan, the construction of the Jiujiang Yangtze River Bridge will continue and the roads will be opened to traffic in the first quarter of 1990. Therefore, the design task of steel beams is very urgent. Jiujiang Bridge is made of domestically produced 15MnVNq steel. There are no design parameters for 15MnVNq steel in the current railway bridge regulations. To this end, the Ministry of Railways Bridge Engineering Bureau, Surveying and Design Institute has summarized past test data and integrated research results that can be referenced at home and abroad. , Proposed “Articles and Explanations for the Design Rule of 15MnVNq Steel Pressure Bars for Jiujiang Yangtze River Bridge” (Discussion Draft)” and “High-strength Screw for 15MnVNq Steel of Jiujiang Yangtze River Bridge”
