DYNAMIC LOAD ANALYSIS OF UNDERGROUND STRUCTURE UNDER EFFECT OF BLAST WAVE-中国期刊网

摘要 Asemi-analyticalmethodofsolvingtheproblemofdynamicstressconcentrationofarbitraryundergroundstructureundertheeffectofblastwaveswasintroduced.UsingtheFouriertransformtheory,theshockwaves(intheformsofSH-waves)canbeconvertedintofrequencybands.Afteremployingcomplexfunctionsandconformalmapping,theadmittancefunctionsofvariousundergroundstructureswereobtained.Then,theproblemofthetimedomaindynamicstressresponseofundergroundstructurecanbeeasilysolvedthroughtheFourierinversetransform.Atlast,theresultsandcurvesofthedynamicstressforthesquare,triangleandhorseshoecavitywerepresented.
