| 摘 要： | 某新建建筑由于转换大梁荷载过大，其托梁在施工阶段无法满足要求，需对托梁进行临时加固处理。采用体外预应力对托梁进行施工阶段的临时加固，施工完成后再撤除体外预应力筋。采用该方法加固见效快，施工工艺简便。 |
| 关 键 词： | 梁 体外预应力 加固 |

| Abstract: | Because of lar ge load of transformation beam, the trimmer beam must be strengthened temporarily. The external prestressing strengthening technology is adopted at the construction stage and removed after construction. Practice proved that strengthening effect is good and the construction is convenient. |
| Keywords: | beam external prestressing strengthening |
