| 預(yù)應(yīng)力混凝土連續(xù)彎箱梁橋抗扭性能試驗(yàn)分析(49 卷) |
| 英文標(biāo)題 |
| Analysis of torsional test for prestressed concrete continuous curved box-girder bridge |
| 摘要 |
| 由于對預(yù)應(yīng)力混凝土連續(xù)彎箱梁橋橫向穩(wěn)定性（抗扭性能）認(rèn)識不足，早期修建的預(yù)應(yīng)力混凝土彎橋大量公共墩內(nèi)側(cè)支座出現(xiàn)全脫空、梁體向曲線外側(cè)扭轉(zhuǎn)和爬移等問題。結(jié)合某立交橋一聯(lián)預(yù)應(yīng)力混凝土連續(xù)彎箱橋出現(xiàn)的病害情況，通過試驗(yàn)分析結(jié)構(gòu)的抗扭性能，并對試驗(yàn)方法進(jìn)行了討論 |
