摘要
介绍桥梁科学研究院在九江长江大桥和孙口黄河大桥关键技术研究中取得的主要成果．这些成果有的填补了我国钢梁设计规范上的空白；有的突破了国外同类规苑的局限性，达到国际先进水平．使我国特大跨度铁路钢桥的设计理论和施工技术得到了更进一步的完善．并提高到了一个暂新的水平．
The chief fruits obtained by the bridge science research institute in the key-technological researches for The Jiu-Jiang Chang-Jiang major bridge and The Sun-Kuo Yellow-River major bridge are presented.Some of these fills the blanks in the design-specifcations of the steel bridges in our country, some overpasses the limitations of the foreign oodes and reaches the intemational advanced level, thus make the design theory and construction technology of the extra-large span steel railway bridges in our country brought country brought to a state of further perfection and raised to a spick and span new level.
