| Analysis of influence of bearing location of simply-supported girder bridge with ballast track on continuous turnout |
| 摘要 |
| 橋上無(wú)縫道岔的受力和變形情況比較復(fù)雜，影響因素眾多。以單組18#單開(kāi)道岔鋪設(shè)在簡(jiǎn)支梁橋上為例，建立道岔—橋梁—墩臺(tái)一體化空間計(jì)算模型。利用有限單元法，考慮固定支座在左側(cè)和右側(cè)兩種工況，分析了簡(jiǎn)支梁橋支座位置對(duì)無(wú)縫道岔受力和變形的影響。計(jì)算結(jié)果表明，當(dāng)固定支座 |
