摘要

In this study, the destruction of concrete block using underwater shock wave generated by electric discharge was studied. Initially, the shock wave generated by electric discharge was investigated by optical observation using a highspeed camera and pressure measurement. A comparison of the underwater shock wave generated from the electrode with and without connecting a metal wire was made. A metal wire was connected to an electrode and a high voltage impulsive current was passed through it to generate the underwater shock wave. A hole was made in the concrete block, filled with water and an electrode was inserted into the hole, which acts as a pressure vessel. The electric current was passed through this electrode to generate underwater shock wave for the destruction of concrete block.
