温度荷载下整体式桥台斜板桥的受力性能研究

Study on loaded property of integral abutment slab bridge with skew angle under temperature load

建立了整体式桥台斜板桥的有限元计算模型,分析在温度荷载作用下,斜交角及板桥下部结构各参数的变化对主梁受力性能和主梁伸缩量的影响,并与相应跨径有伸缩装置板桥的受力性能进行比较,得出可供整体式桥台斜板桥工程设计参考的若干结论。

Finite element models for integral abutment slab bridges with skew angles are presented. The author analyse the effect on the loaded property and thermal deformation of main beam with different skew angles and parameters of substructure, under temperature load. Then com- pared with those joint bridges and some conclusions for the design of integral abutment bridges are made.
