Blasting　excavation　is　one　of　the　most　commonly　used　methods　in　road　high　cutting　slope　construction.　Under　blasting　vibration　wave,　highway　excavation　process　and　its　operation　is　directly　influenced　by　the　stability　of　high　cutting　slope.　Therefore,　based　on　the　Lutuo　Road　construction　project,　a　FEM　model　is　established　by　midas　GTS.　The　stress　field,　displacement　field　and　velocity　distribution　and　transfer　laws　is　analyzed　under　blasting　vibration.　Conclusions　about　the　dynamic　response　of　high　cutting　slope　under　blasting　vibration　are　as　follows:　(1)　As　the　explosion　is　close　to　the　slope’s　corner,　a　stress　concentration　mainly　effected　field　is　formed　within　a　certain　altitude　of　the　slope’s　corner.　(2)　The　displacement　and　vibration　velocity　of　the　high　cutting　slope　has　obvious　magnification　along　the　vertical　direction　under　blasting　vibration,　which　is　similar　to　natural　earthquake　effect.　(3)　Millisecond-delay-control　blasting　technology　is　adopted,　so　the　vertical　vibration　velocity　of　the　buildings　which　are　80　m　away　from　the　blasting　source　is　controlled　below　2　cm/s,　which　is　considered　to　be　safe　according　to　the　blasting　vibration　safety　control　standard.　©　2016　Taylor　&　Francis　Group,　London.
