| 内容記述 | The spatial and temporal variability of free-field earthquake ground motion has been analysed with the aid of stochastic field model. The stochastic model developed in this paper incorporates not only the effect of the stochastic variation of the soil properties in space but also the effect of the wave propagation in the horizontal direction. On the basis of the analytical solution and a sample stochastic wave varying in space （x-direction） and time obtained from the digital simulation method, it is found that the Kanai-Tajimi spectrum of a specified point motion can be derived as a special case of the power spectrum obtained in this paper. It is also found that the stochastic spatial variability of soil properties in the horizontal direction significantly affects the spatially inchoherency of ground motion. | |||||
