| 摘 要： | 对基于频率法测试系杆拱桥吊杆索力的计算模型的选用进行了研究，重点分析了吊杆长细比对模型计算精度的影响规律。通过某实际系杆拱桥中吊杆索力的计算分析表明，随着吊杆长细比的不同，不同计算模型的计算精度有显著差异，需要根据吊杆长细比来合理选用计算模型，才能得到合理的计算精度。文章推荐了与吊杆长细比相对应可满足工程精度要求的索力计算模型。

| Abstract: | The calculation model of cable tension tested by frequency method for tied-arch bridge is analysed, the effects law of slenderness ratio on calculation precision are also analysed.The results of an actual cable tension calculation for tied-arch bridge indicate that the precision of models is different obviously with the changing of slenderness ratio.And the model should be selected based on cable slenderness ration to get reasonable calculation precision.This paper proposed a calculation model of cable tens... |
