Abstract

Aimedatthestatusofexplosioncompaction,whichwasnotthoroughintheorystudyand reliedmainlyonengineeringexperiencetodetermineblastparametersinconstructions,asoilexplosioncompactionmodelwasdevelopedwhichwasbasedonplasticmechanicsandmechanicsofexplosion. Therelationsbetweencompactioneffects(compactionrange,compactiondegree)andexplosive parameterswerederivedandverifiedbythefieldtests.Thesevenfieldtestswerecarriedoutinthe holeswiththediameterof48mmandthecorrespondingnon-couplingcoefficientswere2.000,1.714, 1.500,1.333,1.200,1.091and1.000,respectively.Andtheoreticalcalculationsandfieldtestresultswerecomparedbymeasuringthesoildensitybeforeandaftertheexplosion. Investigatedresults indicatethatinthecaseofnon-couplingcharge,thetheoreticalvalueofcompactioneffectincreases withtheincreaseofnon-couplingcoefficient,whiletheexperimentaldatafirstincreasesandthendecreases, arrivingatthemaximumforthenon-couplingcoefficientofaround1.200.Fortheclayey silt,thecompactioneffectwasmorestable,thelargestcompactionrangeattains70cmandthemaximumcompressionratiois1.055. Thedevelopedsoilcompactionformulasafterexplosionaremoreaccurateandtherelativeerrorislessthan6.00%, sothattheseformulascanbeappliedtoengineering practice
