摘要

A simplified empirically-based seismic site response evaluation procedure that includes a measure of the dynamic stiffness of the surficial materials and a measure of the depth to bedrock as primary parameters is introduced. This geotechnical site classification scheme provides an alternative to geologic-based and shear wave velocity-based site classification schemes. The proposed scheme is used to analyze the ground motion data from the Northridge and Loma Prieta earthquakes. Period-dependent and intensity-dependent spectral acceleration amplification factors for different site conditions are presented. The proposed scheme results in a significant reduction in standard deviation when compared with a simpler "rock vs. soil" classification system. The standard deviations resulting from the proposed classification scheme are comparable with the standard deviations obtained using the more elaborate (and costly) code-based average shear wave velocity classification scheme.
