| 鐵路板梁體外預(yù)應(yīng)力加固技術(shù)試驗(yàn)研究(49 卷) |
| 英文標(biāo)題 |
| Experimental study on strengthening technology of railway slab girder by external prestressing tendons |
| 摘要 |
| 以體外預(yù)應(yīng)力在舊橋加固中的應(yīng)用技術(shù)研究為背景，對(duì)缺少設(shè)計(jì)資料的舊板梁進(jìn)行了承載力試驗(yàn)，以試驗(yàn)數(shù)據(jù)為基礎(chǔ)為同類型的板梁進(jìn)行了體外預(yù)應(yīng)力加固。為了進(jìn)一步對(duì)加固后的試驗(yàn)梁進(jìn)行評(píng)定，又進(jìn)行了200萬(wàn)次的疲勞試驗(yàn)，對(duì)評(píng)定結(jié)果做了進(jìn)一步的研究和驗(yàn)證。 |
