In carrying out a research on local site effect of earthquake wave propagation, it is necessary to predict base motions from the observed surface motions. The characteristic method is known to be applicable to linear wave propagation problems as well as to nonlinear. However, little research work has been conducted on this method, even though it can be used to predict base motions by adopting a time domain nonlinear hysteretic effect. The filtering method is also useful in solving the problems. The computer program "SHAKE" is well-known. This method has been verified by several correlation analyses. However, it gives unacceptable amplification in high frequency range because frequency independent damping factor is evaluated only by the effective strain and employed in this method. This paper describes the characteristics method for nonlinear base motion analysis, and investigates its capablity and applicability to the inversion technique.
