9527375 Elgamal This action concerns the analysis and interpretation of downhole seismic records from the Hualien site in Taiwan. Over the past four years, extensive studies of downhole array data from recorded earthquake motions at Lotung, Taiwan, and at the Wildlife Refuge site, Imperial County, CA, have resulted in the identification of a great deal of practically-oriented site and soil dynamic response characteristics. The identification of these characteristics is entirely based on the recorded downhole acceleration data. Through these studies, a system of well developed and integrated techniques has evolved for conducting state-of-the-art analyses of downhole array data. In this project, these techniques are used to analyze the recorded downhole Hualien seismic records. These records are used to identify the site low-amplitude shear wave velocity profile, and shear wave propagation; also the soil dynamic response properties. The primary analysis tools used are optimization routines combined with site amplification codes. Emphasis is placed on the definition of practical analysis methodologies, and design-oriented procedures. ***

9527375 Elgamal这一行动涉及对台湾Hualien遗址的井下地震记录的分析和解释。 在过去的四年中，从台湾Lotung的地震动作以及加利福尼亚州帝国县的野生动物保护地点进行了记录的地震动作的大量研究，导致了大量实用的现场现场和土壤动态反应特征。这些特征的识别完全基于记录的井下加速度数据。通过这些研究，发展出良好的发达和集成技术的系统已进化用于对井下阵列数据进行最新分析。在该项目中，这些技术用于分析记录的井下Hualien地震记录。 这些记录用于识别位点低振幅剪切波速度曲线和剪切波传播。还有土壤动态响应特性。所使用的主要分析工具是优化例程与站点放大代码相结合。重点放在实践分析方法和面向设计的程序的定义上。 ***
