| 内容記述 | The spatial variation of earthquake ground motions is an important factor that should be carefully considered in the seismic design of buried lifelilles such as tunnels and pipelines. The consideration of the spatial variation of ground motions may also have significant effects on the earthquake response of structures with spatially extended foundations or multiple supports. The temporal and spatial variability of earthquake ground motions has been inferred experimentally using data from closely spaced seismograph arrays. In this paper, the earthquake ground motion varying in time-space domain is described analytically by the stochastic wave filtered by a surface soil layer of irregular thickness resting on half space. The SH wave is transmitted to the soil layer from the half space. The analytic expressions of the earthquake responses of irregular ground are based on the perturbation method, and their accuracy is examilled by comparison with the responses computed by the direct boundary element method for many rough surface models consistillg of topography with sinusoidal shape. Finally, an analytic expression for the frequency wavenumber spectrum of the stochastic wave at irregnlar ground surface is then derived | |||||
