| 預(yù)應(yīng)力混凝土軌道梁張拉施工中的變形和應(yīng)力(46 卷) |
| 英文標(biāo)題 |

| 摘要 |
| 介紹預(yù)應(yīng)力混凝土軌道梁材料配合比和力學(xué)性能；軌道梁的張拉控制應(yīng)力和鋼絞線伸長(zhǎng)值， 實(shí)測(cè)伸長(zhǎng)值與理論伸長(zhǎng)值的相對(duì)誤差都在規(guī)范允許范圍內(nèi)；用有限元仿真模型計(jì)算了張拉過(guò) 程中梁體產(chǎn)生的豎向反拱值和梁體應(yīng)力值，結(jié)果表明有限元模型計(jì)算結(jié)果與采用規(guī)范設(shè)計(jì)公 式計(jì)算結(jié) |
