| Construction simulation and stability analysis of large-span single-track railway continuous girder arch bridge |
| 摘要 |
| 以一大跨度連續(xù)梁拱橋?yàn)楣こ瘫尘?，通過對(duì)全橋施工階段仿真模擬和穩(wěn)定分析，研究架設(shè)拱肋后各個(gè)階段主梁的位移、內(nèi)力、拱肋應(yīng)力以及梁拱結(jié)構(gòu)的穩(wěn)定性。研究結(jié)果表明，拱肋架設(shè)和吊桿張拉使主梁的內(nèi)力和位移發(fā)生較大變化，且主梁邊跨和中跨的變化趨勢(shì)不同；施工過程中橋梁結(jié)構(gòu) |
