For researching the characteristic of bubble pulsation by underwater explosion,the PAMFLOW software and the calculation program of bubble pulsation based on JWL formula were chose to study,and the bubble pulsation of infinite water explosion was also calculated by empirical formula.

Underwater ground explosion with explosive charges has a broad application in national defense and country economic construction,such as hydraulic engineering and water-power engineering and so on.

The applicability of scaling laws to underwater explosion models tests;

Method research of charactering vitality of surface warship subjected to underwater explosion;

Numerical calculations!of the bubble pulsation forces of underwater explosions;

The dynamical response of a ship structure subjected tounderwater explosion shock waves;

Experimental study on bubble oscillation formed during underwater explosions;

Physical behaviors of an underwater explosion bubble in a free field;

Calculation of the initial shock wave energy in underwater blasting;

The paper introduces briefly the attenuation rules of blasting vibration velocity and safety criterions, and analyzes the characteristics of blasting vibration frequency, then the underwater blasting tests using RDX are carried out on laboratory condition, with the intent of studying problems such as ground vibration caused by underwater blasting、 vibration frequency and so on.

In this paper,formulae of a industrial explosive in underwater blasting are given on the basis of TNT explosion shock wave parameters for explosion in water and principle of the energy similarty.
