摘要
结合具体工程实例,介绍了小曲率半径连续弯梁桥的受力特点。因其受力复杂、具有空间效应,采用了梁格法对该类桥梁进行计算。根据计算结果对其受力特点进行了深入探讨,并提出了该类桥梁降低施工难度,优化弯梁桥受力的一些措施,对工程具有一定借鉴意义。
Combined with specific project, this paper introduces the mechanical characteristics of the small radius of curvature continuous curved girder bridge. Because of its complex stress state and the spatial effect, the grillage analysis method is adopted for this bridge to calculate. According to the calculation results to discuss its mechanical characteristics in depth and in view of this kind of bridge put forward some measures to reduce the construction difficulty and optimize some of the curved girder bridge. All of these have some reference to the project.
