Effect of Explosive Source on the Elastic Wave Field of Explosions in Soils
(0) Seismic wave is an essentially elastic wave, which propagates in the soil medium, the strength of initial elastic wave is created by explosion source that has an significant effect on the seismic wave energy. In order to explore the explosive energy effect of output characteristics on the elastic wave field, four different work capacity of explosive (I.e., TNT, 8701, composition B and TNT/RDX/AL) were used for studying the effects of the elastic wave pressure and the rise time of stress wave to the peak value of explosion in the soil. All experiment data have been measured under the same geological condition by self-designed pressure measuring system. This study based on the analysis that the initial pressure of elastic wave from the energy output characteristics of explosive. The results showed that this system is feasible for the underground pressure test, the addition of high energy aluminum powder will increase the pressure of elastic wave and energy release of explosions in the soil. The explosive as a seismic energy source used in petroleum and gas exploration should have the properties of high explosion heat and low volume of explosion gas products.
