| 内容記述 | This paper presents a probabilistic method for describing the spatial variability of strong earthquake ground deformation. The intent is to establish a practical procedure to deal with the effect of earthquake on long extended structures. The principal idea of the procedure presented in this paper exists in the interpretation that the seismic ground displacements in a surface plane are resulted from the homogeneous Gaussian space-time process with zero mean. This interpretation makes it possible to derive the extremes of ground displacements, ground strains, and relative displacements between two points on ground surface which are the important factors in seismic design of underground structures, from the spatial correlation functions. Applying the procedure into an analysis of dense instrument array data, the behaviors of these extremes are summarized in a "Spatial Variability Spectra of Seismic Ground Deformation". Also a method of digital simulation of seismic ground deformations varying in a horizontal plane is presented. | |||||
