Application of the explosive compaction technology is proposed to solve the problem that conventional high-filled embankment reinforcementproject is costlyand has unsatisfactory effect.,A cavity is formed after blasting in soilunderground,withthe soil around the cavitycompressed under blast loading.The embankment is reinforcedby filling materials into the blasting cavity and compressingthem layer by layer. This paper studies the explosive experiments under nine different conditions and analyzesthe compaction effectunder different water content and compaction degree. The results show thatsoil with lowcompactiondegree and highwatercontent before blastingformsblasting cavities with relatively large radius.The test project carried out on a highwaywith highfilled embankmentdemonstrated that application of thetechnology achieved satisfactory effect with undamagedpavement and slope, shortened duration of maintenance and repair,reduced cost,and reduced impact of road construction on traffic.
