摘要
分析介绍了双向土工格栅处理桥头跳车的作用机理和施工要点,并将其应用于抚顺市乙烯大桥的台背跳车处理中。工程实践表明,双向土工格栅能较好的协调桥台与路堤的沉降差,并避免了"二次跳车"的发生,处治效果良好。
The action mechanism and construction keys of biaxial geogrid in controlling bumping at bridgehead are analyzed and introduced, and this was applied in controlling of bumping at behind abutment of Fushun Yixi Bridge. The construction shows that biaxial geogrid can well adjust the differential settlement between abutment and road embankment and meanwhile avoids ＂second bumping＂. The controlling effect is very good.
