Abstract

Ground motion prediction equation (GMPE), which is typically developed by the regression analysis of seismic records at ground surface, is used to assess seismic hazard for a project site. However, these GMPEs may not be valid for the seismic hazard analysis of projects in deep ground, such as mountain tunnels and disposal sites of nuclear waste. In this study, the surface and downhole records of KiK-net are used to evaluate the applicability of GMPE to deep grounds. Results show that GMPEs developed by surface records overestimate downhole motions. Nevertheless, GMPEs can successfully predict downhole records regardless of the depths of records by the proposed adjustment based on the shear wave velocity of deep ground.
