Abstract

The purpose of this paper is to study the dynamic characteristics of soil deposits during earthquake excitation. Generally, soil deposits are known to exhibit significant nonlinear behavior under strong earthquake excitations. Observation of soil earthquake response from ground surface and downhole data provides the information on the differences between strong motion and weak motion, and the effect of soil nonlinearity during strong earthquakes is also examined. Based on the evolutionary power spectral analysis, simplified wave type separation can be done. The soil amplification due to body waves is quite significant in the present study of three earthquake events. A systematic identification method is proposed to identify the hysteresis behavior of soil deposits. The extended Kalman filtering technique is applied to identify the bilinear model parameters of soil restoring forces during strong shaking.
