| 摘要 |
| 隨著我國(guó)新建高鐵及既有鐵路提速的不斷發(fā)展，大量跨越鐵路的橋梁建設(shè)日益增多。在既有運(yùn)營(yíng)鐵路線施工跨線橋,施工方案的選擇尤為關(guān)鍵，而轉(zhuǎn)體工藝是最能降低對(duì)既有線運(yùn)營(yíng)影響方案之一。目前，國(guó)內(nèi)外對(duì)大型特殊橋梁轉(zhuǎn)體施工研究較多，轉(zhuǎn)動(dòng)體系也均為一橋一特殊設(shè)計(jì)，但是對(duì)輕型人行天橋研究較少。本文結(jié)合襄渝線數(shù)十座人行天橋設(shè)計(jì)，對(duì)輕型橋梁轉(zhuǎn)動(dòng)體系進(jìn)行特殊計(jì)算分析。 |
