| 摘 要： | 索道桥作为悬索体系桥梁,其刚度较小的特性比较突出,对动力特性方面的研究较少。基于积石峡水电站索道桥,建立索道桥动力特性分析有限元模型计算其自振特性。对比了施加不同抗风索系统和增加抗风索索力后的动力特性变化,为索道桥的设计和振动控制提供参考。

| Abstract: | As the suspension system bridge,the cableway bridge has the prominent characteristic of low rigidity,and the less research on the dynamic behavior.Based on the cableway bridge of Jishi Gorge Hydropower Station,the dynamic behavior analysis finite element model of the cableway bridge is established to calculate its natural vibration characteristic.The article compares the dynamic behavior varieties after applying the different anti-wind cable systems and increasing the anti-wind cable tension so as to provid... |
