| 内容記述 | The spatial and temporal variability of free-field seismic ground deformation has been analyzed with the aid of stochastic field theory. The primary purpose of this paper is to quantify the spatial variation of ground motion for the seismic analysis and design of buried lifeline structures such as gas and water supply pipelines. The ground is assumed to be composed of horizontal soil layers, with random thickness and soil properties, resting on rigid bedrock. The seismic wave is transmitted to the soil layers from the rigid bedrock with time lag x/c where x = horizontal coordinate and c = wave propagation speed in the x-direction. This study derives the spatial correlation function of the seismic ground displacement on the ground surface as a function of the following quantities: response velocity spectrum, spatial correlation function of the predominant ground frequency varying ln the horizontal direction, mean value of the equlvalent damping ratio of the ground, mean value of the predominant ground frequency, and wave propagation speed in the horizontal directlon. | |||||
