| 標(biāo)題 |
| 跨線橋墩柱病害原因分析與加固方案(49 卷) |
| 英文標(biāo)題 |
| Analysis on causes of defects in piers-columns of overpass bridge and its strengthening scheme |
| 摘要 |
| 某跨線橋在正常使用過程中墩柱出現(xiàn)較為嚴(yán)重的環(huán)形裂縫，根據(jù)現(xiàn)場情況初步分析，墩柱裂縫應(yīng)為空心板梁鉸接縫施工工藝控制不良及溫度荷載引起。檢測單位對墩柱樁基進行了無損檢測，并采用有限元方法對墩柱病害的原因進行了驗證分析，為該橋墩柱的加固處理提供了依據(jù)。 |
