飞燕式拱桥主桥结构稳定及承载力分析

Structural stability and bearing capacity analysis of fly-swallow type arched bridge main bridge

针对钢管混凝土在大跨桥梁上的广泛应用,主要利用大型通用有限元程序计算分析了某拱桥在各种荷载下的弹性稳定分析,结构动力特性计算,并给出了设计建议,以提高人们对拱桥主体结构受力特性的认识,具有一定的参考价值。

Aiming at the reinforced concrete comprehensive application on the large bridge beam, the elastic stability and structural dynamic characteristics calculation of some arched bridge was analyzed with large universal finite element program calculation under various loads. The design suggestions were pointed so as to enhance the .people＇ s knowledge on the arched bridge body structural bearing characteristics, which had some references value.
