摘 要: 近年来,一些工程施工和设计单位在对斜梁桥进行计算时,为了方便而采用正桥的计算方法,造成了工程不安全或成本上不经济的问题。针对这些问题,本文借助于通用有限元软件ANSYS,对装配式斜梁桥进行模拟,通过计算分析,对在不同跨度和斜度影响下的斜梁桥荷载横向分布进行探讨,并得到了不同情况下汽车荷载横向分布变化规律。通过对荷载横向分布变化规律的分析,得到了斜梁桥荷载横向分布的一些特点,这对斜梁桥的研究和设计有一定的参考价值。
关 键 词: 桥梁工程;斜梁桥;斜度;跨度;荷载横向分布

Abstract: In recent years, some project construction and design department apply the calculation method of main bridge in the calculation of skew girder bridge for convenience, which creates the project unsafety and uneconomicalness. To solve these problems, assembled skew girder bridge has been simulated used general finite element software ANSYS. Through computation and analysis, the paper discusses the effects of different skew angle and span on load transverse distribution of skew girder bridge, and obtains the changing discipline of the automobile load transverse distribution in different situation. Analysing the changing discipline, it obtains some characteristics of load transverse distribution of skew girder bridge. It has some certain reference value to the research and design of the skew girder bridge.
Key words: bridge construction; skew girder bridge; skew angle; span; load transverse distribution
