| 提高超窄橋面加勁梁懸索橋顫振穩(wěn)定的措施研究(50 卷) |
| 英文標題 |
| Study on flutter stability measures for suspension bridge by raising super-narrow deck stiffened beams |
| 摘要 |
| 以劉家峽大橋為例，研究超窄橋面桁式加勁梁懸索橋顫振穩(wěn)定問題，劉家峽大橋橋面寬度在國內(nèi)同規(guī)模橋梁中最窄，主纜重力剛度低，抗風問題較為突出。通過引入換算用鋼量經(jīng)濟性指標，套用平板顫振臨界風速的簡化計算公式，進行結(jié)構措施理論研究，并借助風洞試驗手段研究提高臨界 |
