摘　　要：通过介绍珊瑚砂吹填料工程特性,结合某岛国机场跑道地基处理工程,对吹填珊瑚砂地基处理方式进行比选分析,并针对振动碾压和冲击碾压两种处理方式开展小区试验,通过分析碾压影响深度及沉降变化,最终选用振动碾压地基处理方式。该工程已经完工,取得良好技术经济效益,可为类似工程提供借鉴。The engineering characteristics of dredged coral sand were introduced,and the foundation treatment methods of airport runway in an island country were analyzed and selected.Based on the vibration compaction and impact compaction experiments,the vibration roller compaction method was selected by analyzing the influence depth and settlement variation.The project has been completed and achieved good technical and economic results,which can provide reference for similar projects.
