| Analysis of internal forces in construction process of large-span concrete continuous girder bridge on high speed railway |
| 摘要 |
| 以京滬高速鐵路韓莊運(yùn)河特大橋?yàn)楣こ瘫尘埃瑢χЪ芊ìF(xiàn)澆施工過程中支架和主梁的受力與變形進(jìn)行了計(jì)算分析。結(jié)果表明，支架反力、主梁彎矩、應(yīng)力及變形均滿足規(guī)范和設(shè)計(jì)要求，施工方案可有效地指導(dǎo)主梁各階段的施工，提出的施工過程受力分析方法，可供類似工程參考。 |
