블록별 부지분류 적용 해안시설 영역에서의 HAZUS 기반 지진피해 추정

Abstract

HAZUS-MH is a GIS-based computer program that estimates potential losses from multi-hazard phenomena: earthquakes, floods and hurricanes. With respect to seismic disaster, characteristics of a hypothetical or actual earthquake are entered into 2014년 8월 30일 접수 Received on August 30, 2014 / 2014년 9월 29일 수정 Revised on September 29, 2014 / 2014년 10월 7일 심사완료 Accepted on October 7, 2014 1 한국지질자원연구원 지진연구센터 Earthquake Research Center, Korea Institute of Geoscience and Mineral Resources 2 대림산업(주) 기술개발원 Technology Research and Development Institute, Daelim Industrial Co., Ltd. ※ Corresponding Author E-mail : pungsun@kigam.re.kr 블록별 부지분류 적용 해안시설 영역에서의 HAZUS 기반 지진피해 추정 / 선창국· 천성호 11 HAZUS. Then HAZUS estimates the intensity of ground shaking and calculates the correspondent losses. In this study, HAZUS was used as a part of the preparations of the future seismic events at a coastal plant facility area. To reliably characterize the target facility area, many geotechnical characteristics data were synthesized from the existing site investigation reports. And the buildings and facilities were sorted by analyzing their material and structural characteristics. In particular, the study area was divided into 17 blocks taking into account the situation of both land development and facility distribution. The ground conditions of blocks were categorized according to the site classification scheme for earthquake-resistant design. Moreover, seismic fragility curves of a main facilities were derived based on the numerical modeling and were incorporated into the database in HAZUS. The results estimated in the study area using HAZUS showed various seismic damage and loss potentials depending on site conditions and structural categories. This case study verified the usefulness of the HAZUS for estimating earthquake losses in coastal facility areas.
