초록

이 연구에서는 해남 대흥사 북미륵암 마애여래좌상을 구성하는 석재의 암석학적 특성과 물성을 진단하였다. 이 마애불상은 미문상화강암에 부조되어 있으며, 전체적인 암상은 장석에 포위된 작은 석영 결정들이 미문상 조직을 이루고 있다. 손상도 진단 및 평가 결과, 흑색변색(8.4%)과 균열지수(6.6)에서 높은 훼손율을 보였고, 초음파 속도는 약간 풍화단계의 풍화도지수(평균 0.18)가 산출되었다. 마애불의 표면에 나타나는 손상은 기존 보호각의 영향으로 판단되고, 물성은 자연암반의 구조적 특성과 균열의 직접적인 영향에 의한 것으로 해석된다.

In this study, we investigated the petrographic characteristics and physical property of the Rock-carved Seated Buddha at Bugmireugam hermitage of Daeheungsa temple in Haenam. The Buddha Statue was carved on micrographic granite, and the rock was composed of the fine quartz encircled by orthoclase. The results of diagnosis for deterioration evaluation have shown a highly damage rate of black contaminants (8.4%) and crack index (6.6). The ultrasonic velocity have detected SW (slightly weathered) grade of weathering coefficient (mean 0.18). Various weathering factor on the surface of the Buddha Statue was affected by precious shelter, and physical property with ultrasonic was directly influenced by the structural characteristics and fissure of host rock.
