摘要
研究了新城黄河公路大桥系杆拱结构的加固方案 ,提出了 3种不同的加固方案 ,对 3种不同的加固方案加固后的系杆拱结构进行结构静力参数及动力参数的分析及比较 ,比选出了最佳加固方案 .这项研究为系杆拱结构的加固设计提供了理论依据 。
The serviced plans of a highway arch bridge with longitudinal linking girders over the Yellow River in Lanzhou are studied. Three different plans are presented and compared in the static and dynamic coefficients of the arch bridge. The bestservied plan is gained. The result supplies the theoretical basis for the serviced design of the arch bridge with longitueinal linding girders; it also supplies the reference material of an experience for the bridges of the same kind.
