| 采用PC箱梁與鋼桁組合加勁梁的三塔斜拉橋方案構(gòu)思與分析研究(24 卷) |
| 英文標(biāo)題 |
| Conceptive Design and Analysis on the Three tower Cable Stayed Bridge with Reinforced Beam Assembled by PC Box |
| 摘要 |
| 分析混凝土及鋼梁用于大跨度鐵路斜拉橋中的不足之處。探討預(yù)應(yīng)力混凝土箱梁與鋼桁架組合式加勁梁用于高速鐵路斜拉橋時(shí)的剛度與受力。通過對(duì)有無鋼桁架進(jìn)行計(jì)算比較，分析研究加勁梁的鋼桁架對(duì)改善結(jié)構(gòu)受力，提高跨越能力及提高斜拉橋剛度的效果與作用，得出與無鋼桁架PC箱梁 |
