The objective of this research project is to present the prediction model of ground motion for reasonable seismic design of structural systems on the basis of wave propagation theory and source dynamics.This project consists of two sub-projects: (I) The study on the regional factors to specify the characteristics of ground motions which would occur in Rinku town. (II)The study on prediction model of ground motion for seismic design. Sub-project(I): It has been tried to specify the active fault areas which would be important to evaluate seismic safety of a building structure in Riku town. Those areas are determined by seismic energy quantities radiated along the many faults distributed in Kinki district. Nankai trough and Chuo Kouzousen are selected as the most seismically critical and active fault areas. The soil sediment structures in Rinku town and the geolgical structure from those fault areas to bedrock have also been investigated. Sub-project(II): It has been tried to present the prediction model of ground motion for reasonable seismic design of a building structure to be built in Riku town area. To describe the refined wave propagation path and site effect model, the soil sediment structures in Riku town area and the geological structure from fault areas to the bedrock below the ground surface have been investigated. The ground motion is theoretically modeled by the Green's function from source to site and the simple source function. The validity of the prediction model is verified through a blind prediction test for observed earthquake ground motions at Ashigra valley.

该研究项目的目的是根据波传播理论和源动力学介绍结构系统合理地震设计的地面运动的预测模型。该项目由两个子项目组成：（i）针对区域因素的研究，以指定在Rinku镇发生地面运动的特征。 （ii）地震设计地面运动预测模型的研究。子项目（i）：已尝试指定主动断层区域，这对于评估Riku镇建筑物结构的地震安全非常重要。这些区域由沿金基地区的许多断层辐射的地震能量量确定。南京槽和库祖森被选为最关键和活跃的断层区域。还研究了Rinku镇的土壤沉积物结构以及从这些断层区域到基岩的地理结构。子项目（ii）：已尝试介绍地面运动的预测模型，以合理的地震设计在Riku Town地区建造的建筑结构。为了描述精致的波传播路径和现场效应模型，已经研究了Riku Town地区的土壤沉积物结构以及从断层区域到地面下基岩的地质结构。理论上是通过绿色功能从源到站点和简单源函数对地面运动进行建模的。预测模型的有效性通过对阿什格拉山谷观察到的地震地面运动的盲目预测测试进行了验证。
