Exploring saturated calcareous soil explosion compacting mechanism and effect through the experimental study have great theoretical and practical significance on engineering construction in calcareous soil area. First

longitudinal wave velocity and surface settlement are tested at different moments before and after explosion under different explosive parameters through indoor mini-explosive compacting experiment. And then

wave velocity characteristics and settlement rules are studied to reveal dynamic characteristics of saturated calcareous soil explosion compaction through analyzing and contrasting the test results. It is suggested that high void ratio and particle breakage characteristics of calcareous soil have great impact on compacting effect. After explosion

breakage and compression cavity are formed in the neighborhood of explosion because of calcareous soil particle breakage resulted from the heavy shock of explosion

compression cavity would relax along with time lapse

the explosion compaction process is completed within two hours.
