桥梁下部结构稳定性分析

Stability Analysis of Bridge Substructure

在桥梁施工过程中,下部结构位置的准确性对上部结构乃至全桥都有重要的作用。文章以大足朝阳桥为研究对象,采用空间实体有限元模型,分析桥墩发生偏心后下部结构的稳定性,提出了在正常运营过程中要加强桥梁养护、在施工过程中要严格控制定位误差的建议。

In the bridge construction process, the accuracy of substructure position has an important role on the upper structure and the whole bridge.The article, with Dazu Chaoyang Bridge as the research object, used the finite element model of spatial entity to analyze the substructure stability when the pier had the eccentric,and proposed the recommendations of strengthening the bridge maintenance in the normal operation process and strictly controlling the positioning, error in the construction process.
