| 簡支梁橋上縱連板式軌道無縫道岔溫度力研究(18 卷) |
| 英文標題 |
| Study on temperature stress of welded turnout of continuous-slab-track on simple supported girder bridge |
| 摘要 |
| 橋上縱連板式軌道借助底座板的縱連解決梁端轉(zhuǎn)角對軌道結(jié)構(gòu)的不利影響，通過設置滑動層來削弱梁軌相互作用，這種設計思想對橋上鋪設無縫道岔具有積極的借鑒意義。基于梁軌相互作用原理和有限元方法，采用梁單元和彈簧單元模擬各結(jié)構(gòu)層，建立橋上縱連板式軌道無縫道岔縱向力計 |
