Abstract : This paper discusses several topics associated with the analysis and prediction of ground shock from buried conventional explosions. The paper is not intended to provide detailed equations for ground shock predictions. Other papers in this conference provide such information. Rather, this paper is intended to address topics associated with general methodology and uncertainty. As a background for discussion, the first part of the paper lists and briefly discusses the major parameters which govern the ground shock. Some of the parameters are treated in more detail in later sections of the paper. The second and main part of the paper treats scaling. It attempts to put the usefulness of dimensional analysis, scaling the theoretical calculations in perspective. The third portion of the paper discusses the characteristics of a limited data set with respect to material properties and depth of burst factors. Some brief comments about soil-structure interactions and loads on structures are made in a fourth part. Finally, research needs to enable improvement in conventional ground shock and soil-structure interaction technology are mentioned. (Author)
