摘　　要：孔内碎石锤夯是地基处理的一种施工方法，本文根据吉林某厂２×５万ｍ￣３油罐采用该方法加固地基的设计、施工和检测，取得了丰富的实测资料，碎石桩桩身强度达５５０～８００ｋＰａ，复合地基承载力大于３５０ｋＰａ，该施工方法简单，加固效果显著，在地基处理工程中有很强实用性。Deep dynamic compaction is one kind of construction method in ground treatmentengineering.Based on design,constrtiction and quality test of 2×50000m￣3 large oil vessel founda-tion stabilized by this method in somewhat works in Jilin,abundant meassurement data have beenobtained.After being stabilized the strength of stone columns reaches 550 800 kPa and the bear-ing capacity of composite foundation is great than 350kPa.This kind of method with powerfulpracticability can be constructed easily and result in outstanding consolidation effort in groundtreatment engineering.
