摘要：

The effects on the ground distributions of fragments respectively from the explosion of cylindrical and spherical vessels were investigated using Monte-Carlo simulations, to explore the characteristics of the fragment trajectory term. The results showed that wind shear and turbulence sent the fragments impacting in shorter distances than with no wind, and the ground distributions of fragments with wind shear were almost the same as those with turbulence; the probabilistic confidence intervals became narrower with increasing number of simulations, and the accuracy of the results increased due to the larger number of samples corresponding to the larger number of simulations.
