In spite that there is a strong relationship between the earthquake damage and the soil condition, data related to dynamic properties of soil are not enough in the sense of quality and quantity. It becomes important to make a framework to synthesize and integrate the existing soil data and to combine them with the seismic observation data and microtremor data. Therefore, in this research project, we made databases of varieties of existing soil data and newly developed the object oriented geographical information system where the soil configuration in arbitrary section in Nagoya city is interpolated and the soil amplification is evaluated using dynamic soil model estimated by newly developed regression equation. Also, we made a lot of microtremor measurements at about three hundreds places in Nagoya city. By evaluating H/V spectra of microtremor records, we clarified the predominant periods in the whole area of Nagoya city. Based on the examination of the relationship between the observed periods and the calculated ones using above GIS, the soil profiles up to earthquake bedrock are inversely estimated.

尽管地震损害与土壤状况之间存在牢固的关系，但与土壤动态特性有关的数据在质量和数量方面还不够。建立一个框架来合成和整合现有土壤数据并将其与地震观察数据和微生物数据结合起来变得重要。因此，在该研究项目中，我们制作了各种现有土壤数据的数据库，并新开发了面向对象的地理信息系统，该系统插入了名古屋市的任意部分的土壤配置，并使用新的动态土壤模型评估了土壤扩增开发的回归方程。此外，我们在名古屋市的大约三百个地方进行了许多微型人的测量。通过评估微晶记录的H/V光谱，我们阐明了整个名古屋市地区的主要时期。根据使用上述GIS的观察期和计算出的时期之间的关系，将土壤剖面直至地震基岩。
