| Research Abstract |
Since seismic transfer function of an earthquake motion changes with the geometric conditions, in the case of embankments or grounds on inclined base layer, two or three-dimensional analysis is necessary. In this research, a simple modeling method for seismic transfer function of ground on inclined base layer is proposed by superposing one-dimensional transfer functions on upper and lower sides of the slope. The weighting coefficients are determined by multiple linear regression analysis as the function of the distance from the top of inclined basement and the angle of the inclined basement as parameters. It was confirmed that the transfer function obtained by the proposed method is consistent with the analytical result using the two-dimensional finite element method. An application for making seismic hazard map for local area is examined by the interpolated transfer functions.
