Abstract

In order to study the vibration characteristics of the elastic zone of underground explosion, the key is to obtain the experimental parameters of the radiated elastic wave under the coupling of the site medium and the explosive energy. The rock-like sandy soil is not easily processed into large size model. To study the characteristics of the elastic wave radiated from the tamped explosion, a method was proposed by using 0.125 g TNT spherical charge as the explosive source and taking a $\varnothing$ 1 370 mm×1 200 mm loess sample with replaceable plastic-zone as a carrier for providing the propagation path. The characteristics of the elastic stress wave radiated from the tamped explosion in loess and rock-like sandy soil were investigated. The experimental results show that in the test range, the attenuation laws of the peak of the particle velocity (or displacement) and the variation for the dominant frequency of the particle velocity in the two media are consistent. The peak of the particle velocity (or displacement) for the elastic wave radiated from the tamped explosion in rock-like sandy soil is higher than that of loess, the full width at half maximum and the dominant frequency of the particle velocity are lower than that of loess. The coupling elastic wave energy between the tamped explosion and sandy soil is larger than that of loess. Measured results reflect the difference of elastic wave energy coupling strength of the tamped explosion in loess and sand rock explosion.
