摘要
采用空间板单元对实际的具有纵向坡度的弯连续箱梁桥进行了有限元分析 ,提出了各板的应力和位移分布规律 ,分析该类桥梁的危险区域 ,为实际桥梁的设计与施工提供了可靠的依据 .
The continuous box bridge with bend and slope is computed using the spatial finit plate element method.The distribution laws of the stress components and displacement in every plate are presented.The dangerous regions in the birdge are analyzed.The analysis provides a reliable foundation for the design and construction of practical bridge.
