跨遵义火车站下承式钢管混凝土系杆拱桥设计

Structural design of the arch bridge for steel-pipe concrete poles with down-bearing form crossing Zunyi railway station

介绍了外部简支下承式钢管混凝土系杆拱桥上部结构的主要设计内容,利用桥梁博士结构计算软件,对跨遵义火车站下承式钢管混凝土系杆拱桥进行了结构分析计算,检算结果表明,该桥的结构设计满足规范要求,选定的结构形式和截面尺寸拟定是合理可行的。

The paper introduces the main design contents of the structure upside arch bridge for steel pipe concrete poles with the outward props and down-bearing form. Meanwhile, through using the structure calculating software of bridge beam doctor, it also makes a analysis and calculation for structure. In the end, the check results show that the structure design of this bridge can meet the standard demand. Of course, the elected structure form and cross section size＇s drawing up is also feasible.
