摘要
对国内少见的飞燕式、三片拱钢管混凝土系杆拱桥——鄞县二桥进行基于空间建模的稳定性分析.分别进行了线弹性、弹性大变形及弹塑性大变形的稳定计算,考虑荷载布置、拱肋初始几何缺陷、预应力等因素的影响,总结了些有益的结论,对该类桥梁的建设有一定参考价值.
In this paper, a CFST （concrete filled steel tubular） arch bridge, YinXian Second Bridge, is analyzed using linear and nonlinear methods. Both the material and geometric nonlinear properties are taken into account in the nonlinear analysis. Some conclusions are reached through calculations for different load cases.
