本文简单介绍了通过 Excel 悬链线理论,快速简单地计算斜拉索的无应力长度的方法.以珠海某双塔单索面斜拉桥为例,将本方法的计算、抛物线理论和 ANSYS 软件计算出的斜拉索的无应力长度进行对比,此方法计算出的无应力索长完全可以满足精度要求.为以后斜拉索的无应力长度提供新的计算方法.

This paper introduces the method to calculate the unstressed length quickly and simply by Excel catenary theory. Taking Twin Towers single cable plane cable-stayed bridge in Zhuhai as an example, it compares the calculation method of the cable, parabola theory to ANSYS software to calculate th-e length of stress length, can meet the requirement of precision with this method calculated. It provides a new method to calc-ulate the stress length.
