Abstract:Undergroundexplosionexperimentswiththeexplosionequivalentof100kgTNTwereperformedindifferentgeologicalmediums, suchasloess,sand-gravelcompositeandgranite.Andthe correspondingsurfacegroundmotionsinducedbyundergroundexplosionswereobservedbyaseriesof seismometers.Byusingtheseobserveddata,thesourceparameterswereobtained,aswellasthe seismiccouplingefficiencyrepresentedbythesteadyvalueofreducedvelocitypotentialatlowfrequencies. Experimentalresultsdisplaythatfortheundergroundexplosionswiththesamescaleddepth ofburialandsameexplosionequivalent,theseismiccouplingefficiencywasstronglydependantonthe sourcemediumpropertyinsuchawaythatthemediumstrengthplaysthemostsignificantrolesindeterminingtheseismiccouplingeffectandthenthe orosityandthewatersaturation.Andbasedonthe experimentaldata,thefeasibilityoftheempiricalformulaproposedbyM.D.Denny,etalwasanalyzedinestimatingtheseismiccouplingeffectofundergroundexplosionswiththeexplosionequivalent of100kgTNT.
