Abstract

The materials of sculptured stone property around the Hyeonleung Royal Tomb in Guri consist mainly of high weathered of granitic rocks with magnetite-series. Deterioration characteristics occurred highly with microorganism, soil inflow and black contaminants at the burial mound zone. As a result of deterioration evaluation, stone surface around the burial mound zone show serious comprehensive damage of soil inflow (50.5%) and lichen coverage (47.6%) which are the major damaging factors, and there are about 8.6% of biological growth noticeably in the north side. Surface contaminants and the discoloration had the complex causes. Gypsum occurred between joints of stones and the major contaminant type, darkening which was analyzed organic bodies caused discoloration. From result of ultrasonic velocity measurements, there are mean value of 2,195 m/s with highly weathered (HW) grade. Most of the stone properties showed 4 to 5 weathered grade. Therefore, it turned out that sculpture stone properties require conservation treatments. To remove soil accelerating damage factors and lichen occupying high percents, the cleaning process is necessary and consolidation, rejoining and filling are needed as well. Also, consideration on removing conservation materials containing Ca and e fflorescence is required and retreatments need to be considered.

구리 현릉의 능상석조물은 주로 자철석계열의 흑운모화강암으로 구성되었으며 풍화도가 높다. 손상 특성으로는 미생물 및 토사 유입과 흑색오염물의 발생률이 높게 나타났다. 봉분 부재에 대한 손상도 평가 결과, 토사(50.5%)와 지의류(47.6%)의 피도가 주요 요인으로 나타났으며 북면에서 지의류 외의 생물생육(8.6%)이 두드러진다. 표면오염물은 광물산화와 부재간 이음부에서 석고가 생성되었고 주요 변색양상인 흑색은 유기물에 의한 것으로 해석되었다. 각 단위 부재별 초음파 측정 결과, 평균 2,195 m/s의 속도로 심한풍화(HW)가 진행된 상태이며 대부분 부재에서 4~5등급에 도시되었다. 따라서 현릉의 능상석물에 대한 보존처리가 필요한 상태로 판단된다. 훼손을 촉진하는 토사 및 높은 점유율을 보이는 지의류 등 생물오염 세척과 상당한 풍화가 진행된 부재에 대한 강화 및 접합 충전이 요구된다. 또한 Ca를 주성분으로 하는 보수물질과 백화에 대한 제거 및 재처리 여부에 대한 논의가 필요하다 .
