Abstract:

This report summarizes the results of investigations into the effects on explosion-generated ground motion of the MX system siting environment in alluvial valleys. The objective of the analyses described in the report has been to develop a better, quantitative understanding of the late-time, low-frequency ground motion expected in such environments in order to provide a firmer basis for scaling to untested geologic environments and attack conditions. The studies reported have focused on two aspects of the problem of low-frequency surface waves which dominate the ground motion generated by blasts in MX valleys 1 definition of site and yield dependence of ground motion characteristics at alluvial valley sites, and 2 possible enhancement of ground motion at sites in alluvial valleys due to surface-wave reverberation.
