摘要
针对斜拉桥结构及受力特点,进行受力关键位置及结构复杂区域的局部部位受力研究。结合有限元法与三维光弹实验,分析了泉州晋江大桥墩塔梁固结区的塔下横梁的受力状况,揭示其局部应力分布规律,确定了拉、压应力超限的位置及其应力集中位置,为该桥的合理设计提供技术依据。
With the characteristics of the structure of cable-stayed bridge, the research of local stress behaviors is necessary while the research of global analysis is carried out. The local region includes some critical positions, some stress concentration regions and some parts with complicated behavior. In this paper,the photoelastic experiment and finite element analysis of Jinjiang Bridge in Quanzhou are carried out. The stress performance in the pier-tower-girder fixed region is discussed and the locations beyond the limit stress and the stress concentration region are found. The analytical results provided a technical according for the rational design of this bridge.
