摘　　要：在全面考虑干振碎石桩挤密、减震、排水 3种作用的基础上 ,分析了干振碎石桩对高速公路液化地基处理后 ,复合地基中的孔隙水压力分布情况。分析表明 ,考虑 3种作用后 ,处理后的高速公路液化地基在地震作用下液化的可能性大大降低。Based on the three aspects of the dry?vibrated gravel column, compaction, seismic reducing and drainage, the pore water pressure of foundation for the expressway treated by the dry?vibrated gravel column has been calculated. The result indicates that the liquefaction potential of the foundation is greatly reduced.

关 键 词：干振碎石桩 地基液化 水平地震反应 孔隙水压力
