公路新旧路基结合部的病害及处治

Analysis on the major diseases and treatment in highway subgrade convergence

结合已有的工程经验,总结出路基结合部的主要病害及成因,并从改造方案的选择、基底处理、边坡清理、台阶开挖、路基填料、路堤加筋、路堤的压实度控制、施工工艺等方面提出了处治方法。

Based on the engineering experience,the paper summed up the major diseases and corresponding causes in subgrade convergence,proposed treatment methods from the point of reconstruction scheme selection,basal processing,slope cleaning,bench excavation,embankment fill,embankment stiffened,embankment compaction control,construction technology etc.
