摘要
基于大跨径或特大跨径等截面拱桥的恒载分布更接近于沿拱轴均匀分布 ,本文推导了拱轴线的新型式—悬索线的拱轴线方程 ,与其它拱轴线型进行了比较 。
The distribution of dead load of the arch brid ge with constant section of large span or extra span is more close to even distr ibution along the arch axis, so the paper derives an arch axis equation of a new type of arch axis ? cable line. It makes comparison with other arch axis, then it devices the calculation formula of dead load internal force and influence lin e of non-articulated arch bridge with uniform section taking cable line as arch axis.
