摘要
为掌握石板坡大桥墩梁固结点的三维应力状态,建立了墩梁固结点结构分析的空间有限元模型,根据施工过程中及成桥后的工况,分别进行了空间有限元计算,得到了墩梁固结点在三种工况下的应力分布情况,检验了设计的安全性与合理性,提出了改善墩梁固结点应力的措施和方法,为设计和施工提供了科学的依据。
In order to acquire the spatial stress distribution of the pier-beam fixed joint, a pier-beam fixed joint finite element space model is established and analyzed in different loading cases. The local stress distribution of the pier-beam fixed joint is analyzed in three loading cases, as a result of which the safety and rationality of the design are verified, and the measure for meliorating stress of the pier-beam fixed joint is proposed, with a rational basis provided for future design and construction.
