| 摘 要： | 研究提出了悬索桥索股调整的精确计算方法,该方法可以计入主塔偏位、索股温度的影响。通过弹性悬链线模型推导了悬索桥基准索股的悬链线简化方法。该法对于中跨主缆调整与精确方法、抛物线简化方法相比精度较高,边跨主缆调整与抛物线法精度接近,误差均较大,但也可满足实际工程需要。

| Abstract: | This paper proposes an accurate calculation method for adjusting suspension strand, which concerns the impact of deflection of main tower and temperature of cable strand. Based on elastic catenary model, the catenary simplified method for suspension bridge＇s standard cable strand is deduced. Compared with the acc- urate method and parabola method, this method has higher precision on main cable adjustment at mid span. Meanwhile it has almost the same precision as parabola method on main cable adjustment at side span. Though the error of the two are all great, the requirement of actual engineering can be met. |

| Keywords: | main cable catenary standard cable strand cable adjustment formula |
