摘 要: | 由于碾压机械施工困难等原因导致路基边缘压实度不能得到保证,形成欠压实区,尤其路基填方过高时,在欠压实区及压实区之间由于沉降差异容易产生纵向通缝。通过对压实不均匀的高填方路基沉降特性进行的有限元模拟分析,比较了不同工况下路基欠压实区与正常压实区之间的的差异沉降,对减少高路堤病害具有现实意义。

Abstract: | The compactness of subgrade shoulder can not be guaranteed due to roiling, difficult construction and other reasons resulting in under-compaction area. Especially where subgrade fill is too high, longitudinal through crack would be caused easily because of different settlements between under-compaction and compaction areas. The settlement characteristics of uneven compacted high fill subgrade is analyzed with finite element simulation and the settlement discrepancies between the under-compaction and compaction areas in different cases are compared, which have realistic meanings to reduce high embankment diseases. |

Keywords: | high embankment under-compaction area uneven settlement finite element |
