摘　　要：细砂作为路基填料使用,必须考虑细砂振动液化的问题。该文通过对细砂液化条件的分析,以及细砂液化试验的研究,探讨作为公路路基填料的细砂发生液化的可能性。结果表明细砂不具备发生液化的条件,填筑的细砂路堤液化风险较小。The fine sand used as the subgrade stuffing must be considered of fine sand vibration and liquefaction.The article analyzes the liquefaction condition of fine sand,studies the liquefaction test of fine sand,and discusses the liquefaction possibility of fine sand used as the highway subgrade stuffing.The results show that the fine sand has no liquefaction conditions and the liquefaction risk of the filled fine sand embankment is smaller.

关 键 词：细砂 路基填料 液化条件 液化试验
