| 摘 要： | 系杆拱桥中吊杆索长均较短，对于短索索力的计算存在相当的难度。对某系杆拱桥吊杆索力基于频率法测试时采用的几种计算模型进行比较分析，同时分析吊杆长细比对模型计算精度的影响规律，得出与吊杆长细比相对应的索力计算模型，可满足工程精度要求。

| Abstract: | The suspender cables in tie bar arch bridge are short, so it is rather difficult to calculate the short cable tension. Several computational models are adopted for comparison and analysis when suspender cable tension of some tie bar arch bridge based is tested in frequency method; In the meantime laws of influence on slenderness ratio of calculation accuracy of models are analyzed, so that the cable tension calculation model corresponding to the slenderness ratio of suspender is obtained to sufficiently satisfy the requirements of project accuracy. |
