Abstract

This paper focuses on the earthquake hazard delineation and physical loss estimation for lifelines and utilities. Emphasis is given to geographic information systems(GIS) and their application to pipeline networks in evaluating the spatial characteristics of earthquake effects. The paper examines the GIS databases for water supply performance obtained for the 1994 northridge. Relationships among buried lifeline damage and various seismic parameters are examined, and the parameters that are statistically most significant are identified. Using GIS data from the Northridge earthquake, the relationships among pipeline repair rate, type of pipe, diameter, and various seismic parameters are assessed.

본 논문은 지진으로 인한 라이프라인과 공공설비에 대한 위험 지역 묘사 및 물리적 손실추정에 중점을 두었으며, 또한, 지리정보시스템(GIS)과 지진영향의 공간적 특성 평가에 사용된 송수관망을 통한 GIS 적용이 강조되었다. 1994년도의 Northridge 지진에서 얻어진 물 공급 능력이 기록된 GIS 자료를 통하여 매장된 라이프라인 피해와 다양한 지진 매개변수들의 상호 관계가 검증되었으며, 통계학적으로 가장 뚜렷한 상호 관계를 갖는 지진 매개변수들이 발견되었다. Northridge지진으로부터 얻어진 GIS 자료를 이용하여 송수관의 손상률, 종류, 직경, 그리고 다양한 지진 매개변수들이 평가되었다.
