Influence of Bedrock on Site Response
https://orcid.org/http://orcid.org/0000-0002-8503-1927
Seismic hazard assessment study cannot be completed without complete understanding of site response of the particular site. Empirically, VS30 is one of the most important parameter for estimation of site response. Site response of two sites having similar VS30 may vary significantly. These variations or uncertainties mainly arise from the variations in dynamic properties and thickness of individual layers and depth of bedrock. This study focuses on the aspect of influence of bedrock depth on site amplification. For this study, strong motion stations of Kik-Net dataset are used, due to availability of surface and downhole sensors and complete information regarding the properties of subsurface soil stratum. These sites are grouped as per VS30 and bedrock depth. Theoretical ground response analysis (GRA) was performed for all these sites using equivalent linear approach. Amplification function obtained from GRA is compared with amplification function obtained from standard spectral ratio (SSR) and horizontal to vertical spectral ratio of surface records (HVSR). Results obtained were presented in the form of variation in amplification spectrum with respect to bedrock depth.
