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.
