| 標(biāo)題 |
| 無(wú)砟軌道連續(xù)梁橋與道岔縱向相互作用規(guī)律的研究(51 卷) |
| 英文標(biāo)題 |
| Study on regularity of longitudinal interaction between ballastless track continuous girder bridge and turnouts |
| 摘要 |
| 建立了無(wú)砟軌道線(xiàn)橋墩一體化計(jì)算模型，用數(shù)值模擬法，以一組60 kg/m鋼軌客運(yùn)專(zhuān)線(xiàn)18號(hào)可動(dòng)心軌道岔布置在連續(xù)梁上為例，通過(guò)兩種類(lèi)型（“門(mén)”形筋混凝土道床、帶限凸臺(tái)的道床板）無(wú)砟軌道橋上無(wú)縫道岔與有砟軌道橋上無(wú)縫道岔基本軌溫度附加力、基本軌伸縮位移的比較，表明：無(wú) |
