Research Planning for Spatial Evaluation of Geotechnical Earthquake Hazards

本项目为研究规划，根据少数民族研究计划资助项目公告（NSF 94-147）提交，用于支持与竞争性研究项目和提案发展相关的初步研究。在过去的五年中，已经有一些研究倡议来模拟岩土地震灾害的空间分布。这种对空间灾害建模的兴趣主要是由于工程界越来越多地使用地理信息系统（GIS）。地理信息系统是分析空间数据和信息的理想平台，可以帮助工程师和官员做出决策。另一方面，对这些危险造成的灾难作出反应的机构已经开始实施灾害反应系统，为处于紧急状态的地区提供服务。将这两种方法结合起来，将把工程分析纳入减轻和应对地震破坏、伤害和生命损失的程序。目标是通过增加液化变形分析能力和引入两个额外的危险因素：地面运动放大和边坡不稳定，来增强现有的空间分析系统，以评估液化导致土壤破坏的可能性。总体目标是在损害评估和灾害（应急）响应系统的背景下研究空间岩土地震危害模型。以下是该项目的第一阶段，即拟定建议的具体目标：*确定岩土地震工程领域中与危险建模有关的出版物、研究活动和个人，并在空间框架内评价这些模型的实施情况。预计液化变形分析将成为重点。*研究损害评估和灾害应对系统的当前发展，确定合作者、系统开发人员，并与国家应急机构建立联系。*评估灾害模型与灾害反应系统的整合。*向国家科学基金会准备一份全面的建议，重点是开发这些岩土地震危险模块，并将其与损害评估和灾害反应系统一起使用。

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.
