摘　　要：拱架卸落是拱桥施工控制的一个重要环节。对四川省资阳市某混凝土拱桥满堂钢管支架的落架顺序进行仿真分析,探讨其在不同落架顺序下拱圈的应力和变形变化规律,强调和验证合理落架顺序的必要性,为类似工程施工提供参考。Dismounting arch frames is an important part in construction control of arch bridges. This paper carries out simulating analysis for dismounting sequence of full steel tube supports of a concrete arch bridge in Ziyang City, Sichuan Province, investigates changing rules of stress and deformation of arch rings in different supports mounting sequences, and emphasizes on and verifies necessity of reasonable supports dismounting sequence so as to provide a reference for construction of similar projects.

关 键 词：满堂钢管支架 落架顺序 梁格法 应力 变形
