摘　　要：贵州省是典型的喀斯特地貌区，公路路线多穿越峰丛深谷地带。为实现生态环保，减少土石弃方，高填方路堤较多，如何减少沉降，提高强度，保证高填方体路基的稳定性非常重要。以贵州省某高速公路 ZK128＋890～ZK128＋990段高填方路基施工为依托，基于对强夯加固理论分析和不同参数条件下高填方路基的试验研究，提出高填方路基有效加固深度经验公式，为高填方施工提供参考。Guizhou Province is located in typical karst landform area,and more highway routes run across peak cluster and valley zones.In order to realize ecological environmental protection and reduce discarded earthwork,most roads pass through these regions in the form of high -fill,therefore,it is very important to reduce sedimentation,improve strength and guarantee stability of high -fill roadbed.Dependent on construction of high -fill roadbed at ZK128 ＋890 -ZK128 ＋990 section of some expressway in Guizhou Province,and based on analysis of dynamic consolidation theory and experimental study of high -fill roadbeds under different parameters,this paper proposes empirical formulae for effective consolidation depth of high -fill roadbeds to provide reference basis for high -fill construction.
