Luna 9615707 This project is for research planning, submitted in response to the Minority Research Planning Grant Program Announcement, NSF 94-147, to support preliminary studies related to the development of a competitive research project and proposal. During the past five years there have been a number of research initiatives to model the spatial distribution of geotechnical earthquake hazards. This interest in spatial hazard modeling was due primarily to the increased use of geographic information systems (GIS) by the engineering community. A GIS is an ideal platform to analyze spatial data and information that can aid in the decision making process of engineers and officials. On the other hand, agencies that respond to the catastrophes produced by these hazards have moved forward to implement disaster response systems that serve the areas in a state of emergency. An integration of these two approaches will incorporate engineering analyses into the procedures for mitigation and response of earthquake damage, injuries, and loss of life. The goal is to enhance an existing spatial analysis system that evaluates the potential for soil failure through liquefaction by adding a liquefaction deformation analysis capability and by introducing two additional hazards: ground motion amplification and slope instability. The overall goal is to study spatial geotechnical earthquake hazard models in the context of damage assessment and disaster (emergency) response systems. The following are the specific objectives for the first phase, namely proposal development, of this project: * Identify publications, research activities and individuals related to hazard modeling in the area of geotechnical earthquake engineering, and evaluate the implementation of these models in a spatial framework. A focus on liquefaction deformation analyses is anticipated. * Study the current development of damage assessment and disaster response systems, identify collaborators, system developers and establish contacts with national emergency agencies. * Evaluate the integration of the hazard modeling with disaster response systems. * Prepare a comprehensive proposal to NSF focused on the development of these geotechnical earthquake hazard modules and their use with damage assessment and disaster response systems.

Luna 9615707该项目用于研究计划，以响应少数民族研究计划赠款计划公告，NSF 94-147，以支持与竞争性研究项目和建议的开发有关的初步研究。 在过去的五年中，已经进行了许多研究计划，以模拟岩土技术地震危害的空间分布。对空间危害建模的这种兴趣主要是由于工程界增加了地理信息系统（GIS）的使用。 GIS是分析可以帮助工程师和官员决策过程的空间数据和信息的理想平台。另一方面，对这些危害产生的灾难做出反应的机构已向前迈进，以实施服务于紧急状态地区的灾难响应系统。这两种方法的整合将将工程分析纳入缓解和反应地震损害，伤害和生命损失的程序中。 目的是增强现有的空间分析系统，该系统通过添加液化变形分析能力并引入另外两个危害来评估通过液化来评估土壤衰竭的可能性：地面运动放大和斜率不稳定。 总体目标是在损害评估和灾难（紧急）响应系统的背景下研究空间岩土地震危险模型。以下是该项目的第一阶段（即提案开发）的具体目标： *确定与岩土技术地震工程领域中与危害建模有关的出版物，研究活动和个人，并在空间框架中评估这些模型的实施。预计将重点介绍液化变形分析。 *研究损害评估和灾难响应系统的当前发展，确定合作者，系统开发人员并与国家紧急机构建立联系。 *评估危害建模与灾害响应系统的集成。 *为NSF准备一项全面的建议，专注于这些岩土技术地震危险模块的开发及其与损害评估和灾难响应系统的使用。
