| 摘 要： | 针对桥头跳车现象,介绍了用柔性搭板处治桥头跳车的方法。通过工程实际应用及现场试验结果表明,土工格室柔性搭板能明显分散局部荷载,减小路基的沉降,同时,能较好地协调桥台和路堤的沉降差,防治桥头跳车病害的发生。

| Abstract: | For bumping at bridge approach,this paper introduces the countermeasures of bumping with flexible approach slab.Through engineering practical application and site test result,it is indicated that geocell flexible slab can apparently separate local load to reduce subgrade settlement;meanwhile it can better coordinate differential settlement in bridge abutment and embankment to prevent the occurrence of bumping failure at bridge approach. |
