摘　　要：依据曲线有限条计算理论,采用fortran编程语言自编程序,对一简支曲线板桥进行分析计算,并与有限元ANSYSY分析结果相比较。由此可得到,有限条方法具有较高的精度,比有限元方法具有更高的计算效率。Based on calculative theory for curve finite strip, the paper adopts ＇ fortran＇ self - compiling language program to analyze and count a simply - supported curve board bridge, and contrasts results of present analysis to one of finite element ‘ ANSYSY＇ analysis. From this it may be known that the finite strip caleulative method has higher accuracy and capacity than finite element ‘ ANSYSY＇ calculative method.
