In this paper, we develop a technique to obtain a theoretical amplification function of layered ground considering the variations of soil parameters and examine the relation between the amplification and the frequency or the period. By expanding the amplification function in the Taylor series about the mean values of soil parameters, we can easily calculate the mean value and the standard deviation of amplification. Through the numerical examples, we compare the theoretical amplifications with simulated ones and discuss the amplification difference of two kinds of layered ground models. We conclude that our theory considering the variations of soil parameters is useful, and modeling the ground and the values of these soil parameters have a pronounced influence upon the amplification characteristics.
