Abstract

Daegokcheon Stream in Daegok-ri, Ulju-gun, is an area with a developed valley and bedrock from Gajisan Provincial Park to the confluence of the Taehwa River across the Yangsan Fault. To measure the rock of Bangudae petroglyphs, the mineralogical weathering, joints, and scours or cavities at the bottom were confirmed. The measurement was carried out for a short period of time on the joint of the bedrock on which the Bangudae petroglyphs were engraved. Compared to the measured value obtained using existing optical fiber (Ch4 150 ㎛), a displacement value of 300 ㎛ was obtained using the non-attached, non-contact type of measuring instrument. In the future, it is inferred that this instrument could be used for various cultural properties if the HSV-value suitable for illuminance and various measurement experiences are stored.

울주군 대곡리 일대의 대곡천은 가지산 도립공원에서 양산단층을 가로질러 태화강 합류지점에 이르는 계곡과 암반이 발달된 지역이다. 계측할 반구대 암각화 암반은 광물학적 풍화, 절리, 하부의 세굴이나 공동이 확인되었다. 본 계측은 반구대 암각화가 세겨진 암반의 절리면을 대상으로 단기간 계측을 수행하였다. 기존 광섬유를 이용한 계측값(Ch4 150 ㎛)과 비교하여 비부착, 비접촉식 계측기는 300㎛의 변위값이 계측되었다. 향후, 시간대별 조도값에 적합한 HSV값의 적용과 다양한 계측경험이 누적될 경우, 본 계측기는 다양한 문화재에 활용이 가능할 것으로 판단된다.
