| 摘 要： | 为了提高索力动力检测精度,考虑索的抗弯刚度、弹性嵌固和弹性支承等因素建立数学物理模型,推导出进行索力和边界条件动力检测的实用公式.该公式当弹性支承刚度趋于无穷时,收敛于不考虑弹性支承的索力动力检测公式.设计了三个试验验证索力和边界条件动力检测方法的有效性,试验结果表明:弹性支承刚度较小时,不考虑弹性支承对动力检测影响的... |

| Abstract: | This paper presents a systematic approach to estimating the cable tension,when flexural stiffness,rotational end restraints and elastic support are taken into account.To estimate the cable tension precisely,the theoretical model considering flexural stiffness,rotational end restraints and elastic support is formed,then the formulas to estimate cable tension and boundary conditions are found and when the elastic support stiffness is infinite,the formulas are the same as the formulas that do not account for t... |
| Keywords: | flexural stiffness elastic support rotational end restraints cable tension dynamic detection |
