The modern bridge structure become more complex. Its three\|dimensional effect is very obvious, and the result of planar analysis can hardly describe the real stress of bridge. Degenerated solid element was applied to analyze WenHui Bridge to know its spatial stress state. The result of analysis shows the spatial effect is very obvious. And its stress state is reasonable.

现代桥梁跨径不断增大,宽度也在不断加宽,受力条件愈来愈复杂,其表现的空间效应越来越明显,单纯的由平面分析很难反应桥梁的实际受力情况。运用实体退化单元对杭州市文晖路立交桥主桥(斜拉桥)进行了真三维空间分析,特别分析了主梁纵、横向的正应力和索塔竖向正应力。分析结果表明该桥的空间效应比较明显,在恒载作用下桥梁的受力比较合理。

This article elaborates on the supporting effect and three-dimensional effect of working place when the surrounding rocks deform at the presence of tunnels.According to the feature curve of the three-dimensional effect of working place,it divides the deforming process of surrounding rock into strong-effect zone and weak-effect zone of three-dimensional effect.The article also reveals the discovery of the uniform decreasing rule after arranging and comparing the strong-effect...

For dense cable system, the modern cable-stayed bridge is an indeterminate structure with high degrees. And the spatial effect of the box gird is obvious. So the result of plane analysis can hardly illustrate the bridge’s real stress state.

For dense cable system, the modern cable-stayed bridge is an indeterminate structure with high degrees. And the spatial effect of the box gird is obvious. So the result of plane analysis can hardly illustrate the bridge’s real stress state. A new-type element——the degenerated solid element was used to analyze the spatial stress state of the cable-stayed bridge under permanent loads. During analyzing, the three-dimensional effect of prestress force was analyzed. The result of analysis shows that under the permanent loads, the transverse distribution of longitudinal direct stress is very asymmetry, the longitudinal stress in limb of girder is obviously smaller than that in middle part, and that the transversal stress in intercross of pylon and girder goes beyond the limit of material intension. It offers the warranty for consummating the design of Linhai Bridge, and helps to assure the structure’s safety in design.

现代斜拉桥多采用密索体系,属高次超静定结构,且箱 形的主梁结构空间效应明显,单纯地由平面分析很难反应桥梁 的实际受力状况。以一独塔单索面斜拉桥为背景,采用新型空 间单元———实体退化单元,考虑三向预应力效应,对其成桥状 态下的纵、横、竖向的正应力状况进行了分析。分析结果表明, 该桥在恒载下,主梁顺桥向正应力沿横向分布相当不均匀,翼 板上的顺桥向正应力明显小于主梁中间部分的正应力;塔梁相 交处主梁的横桥向拉应力偏大。空间分析结果为完善设计提 供了依据,确保了桥梁在设计上的安全。
