摘要
山区地形地貌多变,地基条件复杂,高填方路堤的不均匀变形和失稳破坏时有发生.针对山区高路堤的基本特点,利用有限元法分析了平坦地基上高填方路堤的工程特性及不同填方高度、软弱地基厚度、填筑速率、压实度下山区高路堤的弹塑性固结问题,得出山区高路堤变形与破坏问题的规律.利用此规律可以较为全面地认识山区高路堤的变形与破坏形态,有效地指导实际施工.
The asymmetric deformation and stability loss of high embankment happened frequently in mountainous area.Based on the main features of high embankment in mountainous area,finite element analysis is made on the engineering behaviors of high embankment in flat ground under complex conditions with the consideration of different fill heights,different soft soil thicknesses,different filling speeds and different compaction degrees.The relations between deformation and stability of high embankment are obtained.Th...
