Economic Consequences Due to Lifeline Failures: Lessons Fromthe Heartland Floods of 1993 for Earthquake Recovery Planning

[322386] Nigg这项拨款是探索性研究小额赠款项目的一部分，目的是对1993年夏季发生在美国中部各州的洪水造成的经济后果进行为期12个月的研究。调查将集中在得梅因和波尔克县，爱荷华州的经济部门中断，由于生命线系统的多重故障。之所以选择大得梅因进行深入研究，是因为整个社区都出现了大规模的生命线故障，这种情况很可能反映了大都市地区发生大地震后的情况。该项目与美国国家科学基金会的民用基础设施系统研究计划有关。通过调查一个社区因灾难而发生的多个基础设施故障，我们将了解这些系统对社区经济福祉的相对重要性。生命线地震工程技术委员会将开展一个以生命线工程为重点的补充项目。* * *

9322386 Nigg This award is made under the Small Grants for Exploratory Research program to conduct a twelve-month study of the economic consequences of flooding in the mid-central states that occurred during the summer of 1993. The investigation will focus on disruption of the economic sector of Des Moines and Polk County, Iowa due to the multiple failure of lifeline systems. Greater Des Moines was selected for intensive study because of the massive lifeline failures across the community, a condition which is likely to reflect the conditions arising from a large earthquake in a metropolitan area. The project is related to NSF's Civil Infrastructure Systems Research initiative. By investigating multiple infrastructural failures in one community due to a disaster, we will gain a perspective on the relative importance of these systems for the economic well-being of a community. A complementary project focusing on lifeline engineering will be carried out by the Technical Council on Lifeline Earthquake Engineering. ***
