In this research, the "Equivalent Single Degree of Freedom method" is proposed and is based on the results of static push-over analyses of many grounds with various properties. A comparison was made of waveforms of multi-layered ground and that obtained from the proposed method using dynamic analysis. It was then confirmed that these waves are almost identical, and that the proposed method is applicable to the evaluation of the surface motion. Even if only a few data with regard to soil properties property is available, particularly in case of an existing railway facility, the proposed method enables economical dense calculation of trackside surface motion. These sets of waveforms will be utilized to identify locations where devastating damage is will be expected in the case of a strong earthquake.
