摘要
以北京市通州温榆河西路跨坝河桥为工程实例,结合梁格分析法,建立空间梁格模型,同时考虑斜桥空间上的弯扭耦合效应,得到桥梁上部结构的内力与变形;通过与单梁模型的对比,揭示了斜桥的受力特性,以期为斜桥的设计提供参考。
Taking Beijing Tongzhou West Wenyuhe Road Bridge spanning Bahe River as an engineering example,combined with the beam grillage analysis method,the spatial beam grillage model is established.At the same time,the bending-torsional coupling effect in the space of skew bridge is considered,and the internal force and deformation of the bridge superstructure are obtained.Through the comparison with the single-beam model,the force characteristics of the skew bridge are revealed in order to provide the reference for the design of skew bridge.
