| 摘 要： | 使用计算软件如ANSYS等对其进行结构动力计算时，建模过程比较繁琐。随着钢管混凝土拱结构的广泛应用，对钢管混凝土拱的关键点坐标计算是必不可少的。本文通过对北盘江大桥钢管混凝土拱关键点的坐标计算，总结出平面拱关键点坐标的计算方法。

| Abstract: | When using limited-element method to analyze the character of steel-pipe concrete structure,some calcutaled software are used,such as ANSYS,but the molding process is trivial with the large scale of using the steel-pipe structure,during analysis it is necessarily to calculate key-point coordinate.This paper summarize the calculated method of key-points coordinate belonged to plane arch basing on the coordinate's calculating of Beipanjang bridge. |
