摘要
以贵州省仁怀市东门河大桥钢拱拱架现浇施工为例,利用空间通用有限元软件Midas/Civil建立空间模型,对各施工阶段拱架的整体稳定性进行了分析,并指出为保证钢质轻型拱架的整体稳定性,必须加强横向联系。
With steel arch frame cast-in-place construction of bridge over Dongmen river in Renhuai of Guizhou as example, the spatial model was built with spatial common finite software Midas/Civil. The integral stability of arch frame during every construction stages were analyzed, it pointed out that in order to assure steel light arch frame integral stability, the cross connection should be strengthened.
