| 預(yù)應(yīng)力混凝土箱梁齒板張拉破壞分析與對(duì)策(50 卷) |
| 英文標(biāo)題 |
| Analysis of recoil-plate fracture during tensioning of prestressed concrete box-girder and its countermeasures |
| 摘要 |
| 某預(yù)應(yīng)力混凝土連續(xù)箱梁橋次中跨和邊跨合龍段頂板鋼束在張拉中導(dǎo)致齒板和頂板的崩裂破壞。從局部承壓區(qū)破壞理論出發(fā)對(duì)齒板和頂板產(chǎn)生破壞的原因進(jìn)行了定性分析。結(jié)合局部承壓區(qū)受力計(jì)算、實(shí)際探察以及處理措施，對(duì)預(yù)應(yīng)力混凝土箱梁鋼束張拉齒塊的設(shè)計(jì)與施工提出了幾點(diǎn)建議。 |
