Abstract:

The propagation and reflection rule of shock wave in vertical shaft under interal explosion is analyzed systematically. Based on the elastic theory, the dynamic equation is built; and the calculation formula of dynamic response of vertical shaft is derived; and the maximal radial displacement and internal force distribution of side wall of vertical shaft are obtained. The calculation results show that the location of the maximal radial displacement of vertical shaft is in the middle of shaft, which is related with the height of explosion; and as the increasing of the explosion height, the location of maximal radial displacement moves to the shaft mouth; but its amplitude become less.

Key words: vertical shaft, internal explosion, shock wave, dynamic response, cylindrical shell
