空腹式石拱桥不对称拆除施工优化分析

The Optimization and Analysis of Asymmetric Demolition Construction for Open-spandrel Stone Arch Bridge

以一座石拱桥拆除施工为例,详细介绍了石拱桥结构的受力特点,分析了空腹式石拱桥不同拆除方案对结构受力状态的影响,并对该桥的拆除施工顺序进行了优化分析,可为今后类似工程的拆除施工和加固设计提供参考。

Combined with the demolition construction of a stone arch bridge, this paper introduced thestress characteristics of the stone arch bridge structure in detail. It also analyzed the influence of the differentdemolition scheme on the structural stress state of the open-spandrel stone arch bridge, and it had optimizationanalysis of the bridge demolition construction sequence, which provided the reference for the demolitionconstruction and reinforcement design of the later similar projects.
