The invention discloses a dual-curing epoxy resin-vinyl ester resin adhesive used for leaking stoppage and reinforcement of underground engineering fractures. The dual-curing epoxy resin-vinyl ester resin adhesive comprises a component A and a component B; the component A comprises epoxy resin, flexible epoxy resin, vinyl ester resin, an unsaturated epoxy compound and the like; and the component B comprises a modified ketimine curing agent and an initiator. The adhesive not only has the characteristics of ultra-fast curing of the vinyl ester resin, but also has the excellent properties of ageing resistance, high toughness, high elongation at break, high bonding strength with wetted-surface concrete and the like of the epoxy resin, and is particularly suitable for the leaking stoppage and reinforcement of the underground engineering fractures.
