摘　　要：对碎石桩复合地基抗液化设计方法进行了分析评价 ,并对施工技术作了介绍。基于复合地基抗地震液化作用的分析 ,提出一种合理的抗液化设计方法 ,该方法能够体现碎石桩复合地基的加密、排水和减震三方面的抗地震液化作用。An evaluation of current design methods of composite foundation of g ravel pile for the liquefaction resistance is presented.Also,an overview of cons truction techniques is briefly discussed.Based on analysis effectiveness of grav el pile for the resistance of soil liquefaction during earthquake,the effects of densification,drainage and seismic reducing should be included in a proper liqu efaction?resistance design method.

关 键 词：复合地基 碎石桩 抗液化设计
