随着经济的发展,广东的城市交通、市政道路与高架桥工程快速发展,但由于施工过程中技术处理不当造成很多路桥相连处出现桥头跳车现象,给后期养护工作带来很大困难。如广州华南路二期工程,内环路广花、广园放射线工程广园西高架桥改造工程刚投入使用不久就出现严重桥头沉陷、跳车现象,既使桥头接缝、砼板遭到破坏,又影响了行车舒适与安全。根据在建的华南路三期工程,针对桥头跳车现象进行综合分析,总结施工过程中应注意的问题,供同行参考。
With economic development, urban transport, municipal roads and viaduct projects in Guangdong are developing rapidly. However, due to technical improper handling during construction, many bridge-jumping phenomena occur at the junction of road and bridge, which poses great difficulties for post-conservation work. Such as Guangzhou South Road Phase II project, the wide loop within the Huayuan, Guangyuan project Guangyuan Guangyuan viaduct reconstruction project just put into use soon appeared serious bridge subsidence, jumping phenomenon, even if the bridge joints, concrete slab was damaged, But also affect the driving comfort and safety. According to the construction of the South China Road Phase III project, a comprehensive analysis of the phenomenon of bridge jumping at the end, summarize the construction process should pay attention to problems for peer reference.
