Abstract

The objective of the study is to develop attenuation equations of the ground motions in the southern part of the Korean peninsula. The earthquake source characteristics and the medium properties were estimated from available instrumental earthquake records and used as input parameters. The peak ground accelerations(PGA) and pseudo-velocity response spectra(PSV) were simulated by the random vibration theory. The attenuation equations for the PGA and PSV were constructed in terms of local magnitudes and hypocentral distances.

본 연구의 목적은 한반도 남부 지역에서의 지진동 감쇄식을 개발하는 것이다 활용가능한 계기 지진 자료로부터 지진원 및 지반 매질의 특성을 추정하고 그 값을 입력 요소로써 사용하였다 확률진동이론에 의하여 최대 지반가속도 및 의사 속도 응답스펙트럼을 모사하여 이로부터 최대지반 가속도 및 의사 속도 응답스펙트럼에 대한 감쇄식을 지역규모 및 진원거리의 함수로 개발하였다
