桥头跳车现象不仅大大影响了行车的舒适性,降低了道路的通行能力,而且是道路交通安全的重要隐患之一。文章介绍了楔型柔性搭板技术在厦门五显一桥桥头跳车处治中的工程实践,阐述了其处治思路和设计方案,施工工艺,注意事项和质量标准。现场检测成果表明:台背经土工格室柔性搭板加固后,近桥台强度和抗变形能力明显提高,较好地实现了桥台与路堤之间的刚柔过渡,从而保证了两者的变形协调。
The phenomenon of bridge jumping not only greatly affects the driving comfort, reduces the traffic capacity of the road, but also is one of the important hidden dangers of road traffic safety. This paper introduces the engineering practice of the wedge flexible lopping technology in the treatment of the bridge jumping at Wu Xian First Bridge in Xiamen, expounds the treatment ideas, design schemes, construction techniques, precautions and quality standards. Field test results show that: After the back of the geocell flexible slab reinforcement, the abutment strength and deformation resistance improved significantly, the bridge and abutment to achieve a better transition between rigid and soft so as to ensure that the two Deformation coordination.
