| 預(yù)制混凝土箱梁快速降溫的措施及效果分析(50 卷) |
| 英文標(biāo)題 |
| Rapid temperature-reduction measures and effect analysis of prefabricated concrete box-girder |
| 摘要 |
| 在客運(yùn)專線建設(shè)過程中，預(yù)制箱梁占據(jù)了重要地位。預(yù)制箱梁施工中，梁體溫度過高，降溫速率過慢，嚴(yán)重影響了箱梁的施工質(zhì)量和工程進(jìn)度。針對該問題，提出了在預(yù)應(yīng)力孔道中通入循環(huán)水等降溫措施，并對采取不同措施的預(yù)制箱梁進(jìn)行了溫度測量，將其結(jié)果做了對比分析。測量結(jié)果顯 |
