摘　　要：对采用爆炸挤淤处理软基的堤身合龙段施工方法进行探讨。针对不同堤身断面类型及场区施工环境条件提出全断面推进法、两侧推进法和单侧推进法3种施工方法,从合龙段位置的选取、长度的确定、抛填方法、抛填材料规格要求、爆炸参数等方面阐述合龙段施工的技术要点,并且结合工程实例介绍上述施工方法的应用情况。This paper describes the closure segment construction on soft ground treated by explosive compaction. For different cross-section types, the paper presents three types of construction methods： the whole section to promote the law, both sides of the marching method and unilateral advancing method. As the technical points, closure segment position selection, determination of the length, with filling material specifications, and explosion parameters are described. In combination with the engineering practice, the paper introduces the application of the methods.
