摘要
以广州新光大桥中拱肋为研究对象,采用大型空间有限元分析程序,进行桥梁的稳定性分析。重点讨论横撑样式、横撑间距以及主拱肋对拱肋稳定性的贡献。
Here we have an analysis on stability of Xinguang bridge by taking the middle arch rib of the bridge as object to be studied through three-dimension finite element program, and elaborate the contribution of cross stay style and space, main arch rib to the stability of arch rib.
