Abstract

Summary

Engineering bedrock depth models plays crucial role estimating the site effects since a damaging earthquake hits the regions prone to seismically active areas. Sediments thickness is one of the important parameters in seismic hazard assessment. Seismic station’s bedrock depths and ground response also have importance in earthquake hazard studies and site classification schemes. Within this context, engineering bedrock depths were estimated for four installed stations in Kocaeli basin and its vicinity and compared with the borehole data. It was carried out active and passive seismic methods (MASW and H/V) to determine shear wave velocity and resonant frequencies and v0 for the velocity depth function. In this regard velocity-depth functions were used and bedrock depths were estimated for per station between the range of 50 and 200 meters. Most of the results show a good compatibility with the borehole data. Subsequently transfer functions were calculated for uniform, damped soil on rigid rock model. Besides, Obtained parameters put these information into service to establish better seismic hazard assessments and will be useful for hybrid classification schemes.
