摘　　要：超深基础振冲碎石桩施工处理后,地基得到明显改善,其抗液化性能、承载和抗变形能力得到提高,并增强了原始地基的渗透性。研究成果在上游围堰地基工程中大规模成功应用,为国内深厚软弱地基处理积累了丰富的设计、施工及检测评价经验,具有一定的推广价值。After the construction of ultra-deep vibro-gravel piles,the foundation has been significantly improved,the liquefaction resistance,bearing capacity and deformation resistance of the foundation have been improved,and the permeability of the original foundation has been enhanced.The research results have been successfully applied to a large scale in the upstream cofferdam foundation project.This paper provides rich experience in design,construction,inspection and evaluation on treatment of deep and weak foundation in China,and the experience is also worth of popularizing.
