초록

이 연구에서는 석조문화재의 표면 균열에 대한 깊이와 연장성을 측정하기 위해 창녕 물계서원 원정비를 대상으로 초음파 속도를 활용하였다. 또한 이 원정비의 장기적인 보존관리 방안을 수립하기 위해 재질 및 손상현황을 조사하고, 다양한 비파괴 기법을 활용하여 정밀진단을 수행하였다. 원정비를 이루고 있는 주요 구성암석은 비석의 부위에 따라 달리 알칼리장석화강암, 반려암 및 섬록암으로 이루어져 있다. 손상도 평가 결과, 특히 균열이 비신의 모든 방향에서 두드러진 분포를 보여 안정성을 저해하는 중요한 손상인자로 나타났다. 원정비 재질의 물성평가를 위한 초음파 측정에서는 비신, 대좌, 옥개석 순으로 속도가 빠르게 나타났다. 원정비에 다양한 형태로 발생한 균열들의 현황과 산출상태를 정량적으로 산출하기 위해 초음파를 이용한 To-Tc법으로 균열의 심도를 측정한 결과, 0.6~24.1cm로 다양한 깊이를 보였다.

To measure the depth and extension on the surface cracks of the stone monument, ultrasonic pulse velocity targeted at the Mulgyeseowon Stele in Changnyeong was used in this research. Additionally, to establish a long-term countermeasure of management and conservation for this stele, we have investigated the material properties and damage on it and have conducted a precise diagnosis by a variety of non-destructive techniques. Our research has revealed that stones of the stele are composed mainly of three rock types according to the parts of it, alkali-feldspar granite, gabbro and diorite. The result of the deterioration evaluation has occurred that cracks, which are observed from every direction in the body of the stele, are the significant factors to reduce structural stability. The ultrasonic velocity for an evaluation on the properties of the stele has revealed that the speed was high in the order of body, pedestal and crown. Furthermore, to understand the present condition and occurrences of the cracks which have measured in many different forms on the stele quantitatively, we have estimated from 0.6 to 24.1cm deep of the cracks by To-Tc method using ultrasonic velocity.
