한반도 지반운동 구현 모델 개발 = Development of the Ground Motion Simulation Model for the Korean Peninsula

국문 초록 (Abstract)

한반도는 지진위험도가 낮은 안정적인 대륙에 위치하고 있다. 최근에 M = 5.0보다 높은 지진이 발생하면 인근 지역의 기존 구조물에 큰 피해가 발생하여 경제적 손실이 발생하였다. 본 연구의 주요 목적은 한반도의 대표적인 지역 지진 특성 (원천, 경로, 현장 효과)을 고려한 지반운동 시뮬레이션 모델을 개발하는 것이다. 개발된 모델의 정확성은 계측된 지반운동과 시뮬레이션된 지반운동의 파라미터 (PGA 및 PSA)를 비교하여 확인하였다.

다국어 초록 (Multilingual Abstract)

The Korean peninsula is located in a stable continental region with low to moderate seismicity. Recently, three earthquake events (foreshockand mainshock of the 2016 Gyeongju earthquake, mainshock of the 2017 Pohang earthquake) with higher than M=5.0 caused economic losswith major damage on existing structures nearby communities. The main purpose of this study is to develope regional ground motionsimulation model with considering representative regional earthquake characteristics (source, path, site effects) for the Korean peninsula. Theaccuracy of the developed model is verified by comparing recorded and simulated ground motion parameters (PGA and PSAs).
