Abstract

Because of using the same rating ranges for every rock types the RMR or the Q-system could not usually consider local geological characteristics They also could not present sufficiently the engineering anisotropy of rocks. The canonical correlation analysis was carried out with 3 kinds of face mapping data obtained from granite, sedimentary rock and phyllite in order to clarify a discrepancy between rock types. According to analysis results, as a type of rocks changes, RM factors have different influences on the total rating of RMR.

국내에서 터널 설계 시 널리 사용되는 RMR 분류법과 Q-system은 모든 암종에 대해 동일한 배점 체계를 적용하기 때문에, 지역적인 지질학적 특성을 반영할 수 없으며 암반의 공학적 이방성을 충분히 표현하지 못한다. 본 연구에서는 암종별 지질학적 특성차에 의한 각 RMR 항목의 중요도를 살펴보기 위하여, 퇴적암, 화강암, 천매암을 기반암으로 하는 터널을 대상으로 막장관찰자료에 대해 정준상관분석을 실시하였다. 분석결과에 의하면 암종의 변화에 따라 전체 RMR배점에서 각 인자가 차지하는 영향은 서로 큰 차이를 보였다
