摘　　要：通过工程实例 ,介绍了采用振动挤密碎石桩法对新近吹填粉煤灰地基土层的处理方法、施工工艺及效果。检测结果表明 ,处理后的复合地基承载力提高一倍以上 ,并消除了地震液化可能性。经济效果显著 ,可对类似场地的工程设计。Introduces an engineering case,and the treatment method,construction technology and treatment effect of the foundation soils by dredger fill with pulverized-coal-ash in recent period, which is the first time to use vibratory compaction crushed-stone piles. The detection results indicate that bearing capacity of the treated composite foundation is increased by one times,and the possibility of seismic liquefaction is eliminated, obtaining significant economic benefits. This can bring certain reference for engineering design and construction for similar site.
