The objective of this research was the development of a high-reliability technique of microzonation for the purpose of urban earthquake hazards reduction. The major results achieved in this research are summarized as follows.1. Discussion was made on the estimation of soil amplification of microseism and its application to seismic microzonation. It deals with a period range of 1-10 sec, and is based on long-period micro-tremor measurement. Soil site/rock site simultaneous observations were performed in the Valley of Kyoto and the San Francisco Bay Area. On this basis, effects of the geological and geotechnical conditions on the soil amplification were discussed in detail, and its applicability to seismic microzonーation was verified.2. Nonlinear soil amplification in a short period range of 0.1 - 1 sec was discussed by using an engineering model developed from a simulation technique. The model was verified with the aid of vertical array data obtained in Japan, as well as recordings from the Loma Prieta Earthquake.3. A simulation model was developed to generate strong motions considering source characteristics and path effects.4. The nonlinear soil amplification model was applied to the damage assessment of urban housings in Kyoto Region.

这项研究的目的是开发高可靠性技术，以减少城市地震危害。这项研究中获得的主要结果总结如下1。讨论了微质主义的土壤扩增及其在地震微针中的应用。它涉及1-10秒的周期范围，并且基于长期的微型室测量。在京都山谷和旧金山湾地区进行了土壤地点/岩石地点同时观察。在此基础上，详细讨论了地质和岩土技术对土壤扩增的影响，并验证了其对地震微针对的适用性。2。通过使用模拟技术开发的工程模型讨论了在0.1-1秒的短期范围内的非线性土壤扩增。借助于日本获得的垂直阵列数据以及洛玛·普埃塔（Loma Prieta）地震的录音3。开发了一个仿真模型，以产生考虑源特征和路径效应的强大动作。4。非线性土壤扩增模型应用于京都地区城市房屋的破坏评估。
