| 摘 要： | 介绍了广州市于1992年建造的东风路—先烈路立交桥的基本情况,并分析了该桥的病害。详细介绍了匝道与主桥相连接处主桥的箱梁梁体位置明显倾斜错位这一主要病害,以及采取对单柱支撑的轴位置增加一根柱,来提高梁体整体强度的措施。通过对该桥的加固施工,桥梁结构趋于稳定,有效地延长了桥梁的使用寿命,并控制了投资和节省了工期。

| Abstract: | The basic condition and the disease of the Dongfeng Rd-Xianlie Rd Viaduct built in 1992 in Guangzhou were introduced and analyzed in this paper. Its main disease, the obvious misplacement of box girder in the connection of ramp and the main bridge, was introduced in detail. The measure to improve the whole strength of girder was adding a pillar on the axle place of single pillar supplying. Through the strengthening construction, the bridge structure returned to stability. Otherwise, the strengthening construction not only extended the bridge working life effectively, but also controlled the investment and saved the construction time. |
