| The stress-strain state of a layered cylindrical shell situated in a ground massif under the action of the slot charge of cylindrical shape placed inside the shell's inner layer is investigated. Mentioned system models wave processes occurring when conducting the explosive works for destruction of mines for starting equipment (MSE). As the result of numerical solution of this problem the peculiarities of the stress-strain state of the shell and the surrounding massif are studied. This allows to determine the parameters of explosion, which are necessary for destruction of MSE with simultaneous provision of the seismic safety of surrounding objects. |
