Beschreibung
Zusammenfassung:	A rockmass damage-induced microseismic monitoring method through extracting signal characteristics of each transmission source according to an embodiment of the present invention classifies at least one signal characteristic selected from a group of signal characteristics consisting of duration, ascending time, a maximum amplitude, a relative amplitude, a frequency band, a maximum frequency, and energy of a received signal into rockmass damage-induced microseismic and microseismic by other transmission sources. In addition, by monitoring only microseismic caused by rockmass damage, it is possible to accurately recognize the destruction of a ground structure in advance. 본 발명의 일 실시예에 따른 송신원별 특성 추출을 통한 암반손상에 의한 미소진동 모니터링 방법은 수신된 신호의 지속시간, 오름시간, 최대진폭, 상대진폭, 주파수 대역, 최대주파수 및 에너지로 이루어진 신호특성 군에서 선택되는 적어도 하나 이상의 신호특성을 암반손상에 의한 미소진동과 그 외의 송신원에 의한 미소진동을 분류하고, 암반손상에 의한 미소진동만을 모니터링함으로써 정확한 지반구조물의 파괴징후의 사전인지가 가능하다.
