| 連續(xù)梁橋上無縫道岔合理化布置研究(20 卷) |
| 英文標(biāo)題 |
| Study on reasonable layout of continuous welded turnout on continuous beam bridge |
| 摘要 |
| 為了進一步研究連續(xù)梁橋上無縫道岔-梁-墩合理布置形式,基于梁軌相互作用關(guān)系，建立了“岔-板-橋-墩”一體化空間計算模型，并編制了相應(yīng)程序。計算分析表明：連續(xù)梁跨度應(yīng)適中，建議取為32 m+48 m+32 m的一聯(lián)三跨連續(xù)梁，岔前或岔后距離梁端宜在20 m以上，固定支座宜布置在連 |
