| 摘 要： | “桥头跳车”现象，已成为高速公路的多发常见病害，分析其主要原因是桥头与路基的沉降差所致。通过对在建垫（江）邻（水）高速公路“桥、涵背”回填及处治技术研究，提出合理设置过渡台阶，使用级配碎石作回填材料，铺设土工格栅加强整体性等工程措施，经现场试验检验，处治效果较好。

| Abstract: | This article is about how to solve the problem of bumping at bridge-head which is dangerous to the safety of expressway.First,the reasons are analyzed in detail.Then,the geological setting is considered,the construction technologies are gaven.We try to use graded broken stone as the basic materials,to set the transition step to control the deformation and to pave cross grating to strengthen integrity.After spot test,the effect is good. |
