| 岔橋相對(duì)位置對(duì)橋上無縫道岔受力和變形的影響(51 卷) |
| 英文標(biāo)題 |
| Influence of relative positions of turnout and bridge upon stress and strain condition in welded turnout on bridge |
| 摘要 |
| 為了進(jìn)一步研究橋上無縫道岔受力和變形的特點(diǎn)，通過建立“岔—橋—墩”縱向相互作用一體化計(jì)算模型，分析道岔與橋梁的相對(duì)位置對(duì)鋼軌、道岔、墩臺(tái)等結(jié)構(gòu)部件受力及變形的影響。經(jīng)計(jì)算分析表明，隨著道岔頭部距連續(xù)梁橋左端梁縫距離的增大，基本軌伸縮附加力、伸縮位移、橋墩 |
