guaranteed destruction, underwater explosion, beam structure, reflection effects, attached water mass.

The solution of the problem of guaranteed destruction of a beam lying freely on nondeformable (ideal) supports in water at a depth H by an explosion of a non-contact spherical explosive charge located at a given distance a from the beam is presented. The effects of reflection of the flow of perturbations of the medium from the barrier (beam), the characteristics of the explosive charge, its location relative to the beam are taken into account. The influence of the aquatic environment is taken into account by introducing an attached mass of water.
