摘要
以钢管混凝土拱桥的主拱为研究对象，对拱圈的稳定性进行线性屈曲和非线性屈曲分析，重点分析了横撑对主拱稳定性安全系数的影响，并对横撑的合理布置进行了探讨。
Taking the main arch of concrete filled steel tubular arch bridge as investigated object linear buckling analysis and nonlinear buckling analysis are respectively carried out for stahility analysis of arch ring. The influences of brace on the safety coefficient of stability of main arch are mainly analyzed. Further discussion is also made for the reasonable setting of braces.
