| 摘 要： | 梁桥经过拓宽改建,形成了新、老梁体拼接的组合桥。此类桥梁由于新、老梁体的刚度不同及基础沉降原因出现拼接处开裂、错位等病害。以南奉公路光明桥为例,介绍了此类桥梁的检测、分析、病害修复的过程,对桥梁维修后的运行效果进行了跟踪观测。

| Abstract: | When girder bridge is widened, a combined bridge is formed consisting of both new and old girders. The connecting part of the bridge is tending to crack and transfer because of the rigidity difference in the two beams and foundation settlement. This article uses the Guangming Bridge on Nanfeng highway as an example to introduce the detection, analysis and repair process of this kind of bridge. The tracking and observation results after the reconstruction is also shown too. |
