随着经济的发展,广东的城市交通、市政道路与高架桥逐渐增多。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。如河梅高速公路,刚投入使用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。针对此桥头跳车现象进行综合分析、总结施工过程中注意问题。

With economic development, Guangdong’s urban traffic, municipal roads and viaducts gradually increased. However, due to improper handling of technology in the construction process, many bridge-jumping phenomena occur at the junction of road and bridge, which brings great difficulties to the post-conservation work. Such as Hemei Expressway, just put into use a serious bridge subsidence, jumping phenomenon, even if the bridge joints, concrete slab was damaged, but also affect the driving comfort and safety. Aiming at the phenomenon of jumping at the bridgehead, a comprehensive analysis is made to summarize the attention problems in the construction process.
