摘要
在钢管混凝土拱桥的设计中,稳定问题至关重要,该文针对跨径为338m的钢管混凝土拱桥,利用有限元中的参数编程APDL创建有限元模型,进行该拱桥的特征值屈曲分析,结果表明,该拱桥在运营阶段不会出现失稳现象。
The stabilization issue is very important in the design of the steel pipe concrete arch bridge.The article carries out the bending analysis of the characteristic value of this arch bridge by utilizing the parameter programmable APDL in the finite element to build the finite element model in view of the steel pipe concrete arch bridge of the 338-m span.The result makes clearly that the destabilization appearance of this arch bridge will not happen in the operation period.
