NSF/EPI Workshop: Dynamic Soil Properties and Site Characterization for Earthquake Resistant Design and Analysis

这一行动是为了支持计划于1989年11月9日和10日在旧金山湾区举行的研讨会。研讨会的目的是讨论用于抗震设计和分析的土的动态特性的表征程序。该讲习班是与电力研究所(电力研究所)联合支持的。讲习班将讨论两个主题：(1)在适合用于地震设计和分析的应变水平下，就地估计土壤动态特性的方法，以及(2)这些动态土壤属性的空间变异性的量化方法。研讨会的参与者将根据他们在以下领域的知识和专业知识进行选择：(1)动态土壤特性的现场和实验室表征，或(2)在地震模拟中使用现场和实验室属性。研讨会的形式将包括一系列最新的技术演示，重点是北美、欧洲、和亚洲，以现场估计动态土壤特性，包括它们的空间变异性。一系列小组讨论将讨论与动态财产测量和场地总体特征有关的具体问题，这些问题将在全体会议上介绍。研讨会的成果将是一份文件，确定动态土壤性质测量领域的不确定性和需求，以及抗震设计和响应分析的总体场地特征：it还将提供值得特别研究的主题和优先事项的指南。

This action is for support of a workshop planned for the San Francisco Bay area on November 9 and 10, 1989. The purpose of the workshop is to discuss procedures used to characterize the dynamic behavior of soil for seismic design and analysis. The workshop is being supported jointly with the Electric Power Research Institute (EPRI). The workshop will address two topics: (1) methods for estimating the dynamic properties of soil in situ, at levels of strain appropriate for use in earthquake design and analysis, and (2) methods for quantifying the spatial variability of these dynamic soil properties. The workshop participants are to be chosen for their knowledge and expertise in the areas of either (1) field and laboratory characterization of dynamic soil properties, or (2) use of field and laboratory properties in seismic modeling. The format for the workshop will include a series of state-of-the-technology presentations, focusing on procedures currently used in North America, Europe, and Asia to estimate dynamic soil properties in situ, including their spatial variability. A series of panel discussions will address specific issues related to dynamic property measurement and overall site characterization, and these will be presented at plenary sessions. The product of the workshop will be a document that identifies uncertainties and needs in the areas of dynamic soil property measurement and overall site characterization for seismic design and response analysis: it will also provide a guide to topics and priorities meriting special studies.
