摘要
随着国家西部大开发战略的实施,西部山区高速公路将会大量修建。山区高速公路相对高的平面纵面指标,不可避免地形成高填路堤和深挖路堑。而路基的施工,破坏了山体原有的自然平衡,如果处治不当,随之而来的就是路基病害甚至灾害的频繁发生。文章介绍的采用土工材料处治法是一种非常有效的措施,能较好地治理路基堤堑结合部变形不协调和强度不足引起的坍塌失陷和局部不均匀沉陷等病害。
With the implementation of China's Great Western Devel opment Strategy,lots of expressways in Western mountainous regions will be cons tructed.The expressway in mountainous regions has relatively higher horizontal a nd longitudinal index,which inevitably leads to high filled embankment and deep excavated roadcut.On the other hand,the subgrade construction will destroy the original natural balance of massif.Improper treatment to the above may cause fr equent defect even disaster in the subgrade.The geomaterial treatment presented in the article is a very effective measure,which can properly deal with the def ects such as falling and partial uneven settlement resulting from the inharmonio us deformation and inadequate strength in the connecting part between subgrade,embankment and roadcut.
