비파괴 분석을 활용한 조선왕릉 태릉 석조물의손상특성 분석

Abstract

The Taereung Royal Tomb from the Joseon Dynasty is the tomb of Empress Munjeong, the second queen ofKing Jungjong, and it contains various types of stone artifacts. All of these stone artifacts were constructed usingcoarse- to medium-grained biotite granite. The major types of deterioration of the stone artifacts are identifiedas surface weathering and biological contaminants. Exfoliation (145 sculptures), granular decomposition (138sculptures), and repair materials (156 sculptures), along with biological contaminant algae (154 sculptures), lichen (165sculptures) and moss (97 sculptures), have a high occurrence frequency. In particular, it is deemed that immediateconservation treatment is required, as biological deterioration (algae) represents the most serious condition (grade3 or higher in 94% of all stones), and it is thought that exfoliation and granulation decomposition are required forlong-term conservation management. As a result of equo -tip hardness and ultrasonic measurement, more than70% of stones were found to have very weak physical properties. Through hyperspectral analysis, organisms wereshown to inhabit more than 80% of the surface of burial mound stone artifacts, and P (phosphorus), S (sulfur), Cl(chlorine), and Ca (calcium) were detected in this area. This is because Taereung Royal Tomb has been exposed tothe outdoors for hundreds of years and has been weathered by physical, chemical, and biological factors. Therefore,among the stone artifacts in the Taereung Royal Tomb, those with high physical weathering grades are consideredto require consolidation to reinforce them physically. Since organisms are highly likely to cause stone damage, theymust be removed via dry and wet cleaning. In addition, in order to delay the reoccurrence of organisms followingconservation treatment, it is necessary to regularly clean up the soil that has flowed into the burial mound, and tomonitor conservation conditions over the long term.
