拱桥的现行设计方法都是以试算来确定拱轴系数m,尽管《公路设计手册》(以下简称《手册》)提供了许多计算用表,但实际上拱轴系数m的确定仍然无法摆脱繁琐的试算过程。随着微型机的迅速发展和广泛使用,为拱轴系数m的确定找到了一个极为有效的计算工具。 根据《手册》推荐的方法,我们编写和调试了拱桥微型机计算程序,经考核,可以供参考使用。
The current design method of the arch bridge is based on trial calculation to determine the arch coefficient m. Although the Highway Design Manual (hereinafter referred to as the “Manual”) provides many calculation tables, in fact the determination of the arch axis coefficient m still can not get rid of the cumbersome Trial process. With the rapid development and widespread use of microcomputers, an extremely effective calculation tool has been found for the determination of the arch coefficient m. According to “Manual” recommended method, we have compiled and debugged arch bridge microcomputer program, after examination, can be used for reference.
