摘要：

The dynamic load of underwater explosion of a bottom charge is different from that of explosion of charge in infinite water because of the influences of boundary conditions. The pressure propagation and distribution of bottom charge underwater explosion are studied through model experiments and numerical simulation. Both the experimental and numerical results show that the peak pressure of underwater explosion of bottom charge decreases with the increase in the distance, and the pressure is hemispherically distributed, where the peak pressure is on a side of the charge near sea bottom. ©, 2014, China Ordnance Society.
