摘　　要：饱和砂土地震液化问题是岩土地震工程中一个重要的研究课题。在多种可行的防治液化措施中 ,最普遍的方法是采用碎石桩复合地基。本文结合目前国内外碎石桩复合地基的抗液化研究的最新进展 ,对碎石桩的密实、排水减压和减震作用做了较详细的评述 。Liquefaction of saturated sands remains an important topic in geotechnical earthquake engineering. Amongst various remedial measures available, the use of stone columns is one of the most popular choices. In this paper, a detailed review on effectiveness of densification, drainage and reinforcement of stone columns for the esistance of soil liquefaction during earthquakes is presented. Some problems worthy to be further studied are proposed.
