Abstract
Abstract
Explosion yield estimation based on seismic data (ground motion in the near field) is one common approach to estimate near-surface explosion yield. The near-surface yield estimation models of different site media are usually established through chemical explosion experiments. However, the site media of current chemical explosion experiments are mainly soil and hard rock, lacking the experiment data and yield estimation model of soil-rock-mixture site. To solve the above problem, the seismic (ground motion) data of chemical explosion experiments at different depths in soil-rock-mixture site were gathered to establish the near-surface yield estimation model for soil-rock-mixture site. Besides, analysis was made regarding yield estimation accuracy and effects of rock-soil types on accuracy. The results show that the rock-soil type has great influence on the yield estimation accuracy of near-surface explosions, and the near-surface yield estimation model of soil-rock-mixture site has high accuracy in estimating explosion yield.
