Abstract: To study the action of high-energy explosives in the underground explosion a measurement system for soil pressure is designed, including stress-testing methods and experimental systems. The experimental results show that the pressure measurement system can well record the explosions, as has been done in China and Turkey, as well as the pressure changes and the development processes. Through the analysis of the pressure waveform and the spectrum, we obtain, for the same explosive and the soil media, the stress wave peak value, the principal frequency and the frequency bandwidth against the distance.
