In many research studied on the propagation characteristics in the non-linear soil media, the equivalent linear procedure according to the linear wave propagation theory has been used and also they have been investigated from the point of view that is; the fluctuation of dominant frequency and peak value of response spectra. Meanwhile, there are some earthquake records which are hard to be simulated by the usual elatic wave propagation theory. In this study, the concept of the solitary wave that is sequently generated as the peculiar wave propagating in the non-linear media is applied to soil dynamic problem, the non-linear response analysis for soil model is carried out and the wave transition is investigated by means of the response spectra etc.. Then the main purpose of this study is that the observed soil dynamical behavior should be represented by the analyses in consideration of non-linearity of soil media. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
