Precast　concrete(PC)slab　has　been　increasingly　used　with　the　proposal　and　development　of　prefabricated　structures.　Field　explosion　tests　of　laminated　slabs(1.0m/kg1/3,　0.8m/kg1/3,　and　0.6m/kg1/3)with　differ-ent　explosion　distance　proportions　were　performed　herein　to　study　the　antiexplosion　characteristics　of　the　PC　slabs.　The　an-tiexplosion　test　results　of　ordinary　reinforced　concrete(RC)slabs　with　the　same　explosion　distance　proportions　were　used,　to　compare　and　analyze　the　antiexplosion　properties　of　the　PC　and　RC　slabs.　The　incident　and　reflection　overpressures　and　the　displacement　and　damage　distributions　of　the　laminated　slab　were　measured　in　detail.　The　results　show　that　the　incident　and　reflected　overpressures　are　in　good　agreement　with　the　CONWEP　empirical　formula,　which　verifies　the　validity　of　the　explo-sion　load　in　the　test.　The　deflection　of　the　PC　slab　is　larger　than　that　of　the　RC　slab　under　the　same　working　conditions.　The　main　crack　on　the　back　of　the　RC　slab　depicts　a　wide　bending　damage　mode,　while　the　main　crack　on　the　back　of　the　PC　slab　diffuses　to　both　ends.　The　crack　exhibits　a＇wide　narrow　wide＇staggered　distribution,　indicating　that　the　PC　slab　can　evenly　dissipate　the　explosion　shock　wave.　The　residual　displacement　of　the　PC　slab　is　greater　than　that　of　the　RC　slab　when　the　proportional　distance　is　greater　than　0.6m/kg1/3.　By　contrast,　the　residual　displacement　of　the　PC　slab　is　smaller　than　that　of　the　RC　slab　when　the　proportional　distance　is　0.6m/kg1/3.　No　obvious　cracks　are　observed　in　the　laminated　surface　of　the　PC　slab,　thereby　meeting　the　shear　resistance　requirements.　©　2022,　Editorial　Board　of　Journal　of　Tianjin　University(Science　and　Technology).　All　right　reserved.
