The objective of the project is to propose a comprehensive seismic zoning technique which include the nonlinear soil amplification effect of surface layers at specific site. The major conclusions are summarised as follows.(1)The strong motion array record database has been developed which includes the array records obtained by many research groups in Japan.(2)The conversion factor, beta-model, which has been developed on the basis of simulated ground motion both on rock and soil surface levels, has been verified in the array record database.(3)The strong motion records from the 1989 Loma Prieta Earthquake and the related soil profile information have been arranged for the verification of the beta-factor model. The beta-factor model has been modified on the basis of the data.(4)The technique to incorporate the effect of irregularity of surface deposit on strong motion amplification has been developed. The irregularity index of the layered ground has been proposed for the comprehensive microzoning.

本计画的目的是提出一个综合性的地震区划技术，其中包含特定场地表层土壤的非线性放大效应。主要结论总结如下。（1）建立了强震台阵记录数据库，该数据库包括日本多个研究小组获得的台阵记录。（2）根据模拟的岩、土地面运动建立的转换因子β模型，在台阵记录数据库中得到了验证。（3）整理了1989年洛马普列塔地震的强震记录和相关的土壤剖面资料，对β因子模型进行了验证。根据这些数据对β因子模型进行了修改。（4）发展了考虑地表存款不规则性对强震放大影响的技术。提出了分层地基不平整度指标用于综合小区划分。
