During implementation of explosive compaction of embankment, people usually rely more on the experience and lay less stress on the analysis and research on the project. Taking Lianyungang port 0.3 million DWT waterway engineering phase I as an example, this paper summarizes the supervision control method for the explosive compaction based on the analysis of the test on typical section, regulation of the construction manners and determination of the inspection means, so as to guarantee the effect of explosive compaction and achieve the target of A for the engineering quality. It can provide a reference for similar engineering supervision work.
