Yield Estimation Model and Its Accuracy Analysis for Near-Surface Explosions of Soil-Rock-Mixture Site

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 models of different site media are usually established through chemical experiments. However, current experiments mainly soil and hard rock, lacking experiment model soil-rock-mixture site. To solve above problem, motion) at depths were gathered establish for Besides, analysis was made regarding accuracy effects rock-soil types accuracy. results show that type has great influence explosions, high estimating
