초록
탄성파 축소모형 실험은 탄성파 진폭 등의 반응을 분석함으로써 관련 기술에 대한 실험 및 검증에 이용되어왔다. 국외의 경우 탄성파 축소모형 실험의 연구동향에 대한 연구가 수행되었지만 국내의 경우 탄성파 축소모형 실험의 연구동향 및 전망에 관한 연구는 수행되지 않았다. 따라서 본 연구에서는 약 30년간(1982 ~ 2015년) 수행된 국내·외탄성파 축소모형 실험을 다룬 연구논문을 조사하고 테마 별, 연도별 등으로 분류하여 연구동향을 파악하였다. 분석결과, 국내의 경우 국외에 비해 연구테마가 제한적이었으며, 연간 게재 수에 따른 연속성도 매우 떨어짐을 알 수 있었다. 분석결과에 따라 향후 탄성파 축소모형 실험을 전망했을 때 복잡한 이방성 구조를 가진 모델을 이용한 이방성 특성연구, 복잡한 지질구조의 자료처리를 위한 구조보정과 파형역산, 다양한 탐사 방법에 관한 연구가 탄성파 축소모형과접목되어 수행될 것으로 판단된다.
Abstract
Seismic physical modeling has been used to test seismic survey technologies by analyzing the response of seismic amplitude. International studies on the R&D trend of seismic physical modeling have been performed. However, domestic studies on the R&D trend and prospect of seismic physical modeling have not been performed. Therefore, in this study, seismic physical modeling papers about 30years were investigated to understand the R&D trend of papers classified by theme, year, etc. According to the analysis results, the theme of domestic papers is limited than that of international papers. Also, the number of domestic papers published annually shows poor continuity. Prospecting the following seismic physical modeling with analysis results, the prospect will be expanded to various studies, such as the anisotropic characteristics using a complex anisotropic structural model, waveform inversion and migration for data processing of complex geological structure, various survey methods conducted seismic physical modeling.
