摘要(Abstract)：

在软基处理的各种方法中,爆炸法处理松散砂土地基以其快速、经济、简单的优点为人们所认同。迄今爆炸密实法应用于地基的处理已有70多年的历史,适合于处理饱和、松散的砂土地基,但在我国地基处理中应用不多也不常见,相应的理论研究和设计方法的研究远远落后于工程实践的要求。本文从爆炸密实法发展简史、加固机理及密实过程、爆炸能量输入与衰减的函数、设计参数、处理效果评价指标等几个方面对爆炸密实法的历史及研究现状进行了回顾,并对已有的研究成果进行了简要的评述。
In the treatments of ground foundation the one of blastingdensification of sand is a viable and efficient method,and is well known for its several advantages of speed,economy and simpleness.By now the method has been well used in the treatment of ground foundation for over 70 years in the case of improving saturated and loose sand foundation.Since the method used in treatment of ground foundation is not popular in China the design,study and the resulting theory are far behind the requirements of engineering practice.The paper reviewed the previous work and current engineering practice in terms of the history of Explosive Compaction,densification mechanisms,energy input and attenuation function,design parameters and treatment results.As a conclusion the paper also reviewed the achievements reached in Explosive Compaction.
