| 連續(xù)梁橋上縱連板開裂對無砟道岔受力影響分析(50 卷) |
| 英文標題 |
| Analysis about influence of cracking of continuous track slab on continuous girder bridge on internal forces in welded turnout |
| 摘要 |
| 考慮縱連板式無砟道岔的結(jié)構(gòu)特點，基于無縫道岔、無砟軌道和橋梁間的相互作用關(guān)系，建立了道岔—軌道板—底座板—橋梁—墩臺一體化有限元計算模型。以某高架橋上左咽喉為例,分析了混凝土結(jié)構(gòu)開裂對連續(xù)梁橋上縱連板式無縫道岔群受力與變形的影響。結(jié)果表明，混凝土開裂及整個 |
