| 標(biāo)題 |
| 裝配式斜交空心板橋體外橫向預(yù)應(yīng)力加固研究(51 卷) |
| 英文標(biāo)題 |
| Study on reinforcing skewed assembly hollow slab bridge by external transverse prestressing |
| 摘要 |
| 針對(duì)裝配式空心板橋因空心板之間橫向聯(lián)系弱易出現(xiàn)單板受力的病害，采用MIDAS/Civil有限元程序建立裝配式斜交空心板橋的計(jì)算模型，進(jìn)行多種加固工況計(jì)算。結(jié)果表明：采用體外橫向預(yù)應(yīng)力進(jìn)行加固，增加了裝配式斜交空心板橋各板之間的橫向聯(lián)系，改善了橋梁整體性，加固效果良好 |
