Abstract

The preservation treatment for the outer rampart of Namhansanseong fortress is needed due to partial collapse and separation of stone materials. In this study, we investigated the petrological features of the stone materials used for the outer rampart and estimated their provenances through the geologic survey. Through the above study, the suitable replacement stone in the maintenance of outer rampart were suggested. The stone materials of the above outer rampart consist of the banded gneiss, augen gneiss, granitic gneiss and porphyroblastic gneiss. Among these four kinds of rocks, granitic gneiss is quantitatively the most abundant. Petrological comparisons between stone materials and rocks distributed around the fortress, lead to the conclusion that the above materials are likely to have been delivered from around the fortress. Judging from the results of the comparison on frequency of use and strength characteristics among the above rocks, the granitic gneiss is considered to be suitable for restoration of the outer rampart of the fortress.

남한산성 외성은 성벽의 붕괴와 부재의 탈락으로 인해 보존처리가 필요한 실정이다. 이 연구에서는 남한산성 외성의 성벽부재를 대상으로 암석학적 연구를 실시하고 주변의 지질조사를 통해 산지를 추정함과 동시에 외성의 정비 시 활용 가능한 대체석을 제시하고자 한다. 남한산성 외성부재는 호상편마암, 안구상편마암, 화강암질편마암, 반상변정질편마암으로 이루어져 있으며 화강암질편마암이 가장 많이 사용되었다. 주변에 분포하고 있는 암석의 암석기재적 특징과 야외산상, 남한산의 채석흔적으로부터 남한산을 포함한 일대가 석재의 산지로 추정된다. 외성의 주요 축성재료들의 물성시험 결과와 축성에 사용된 부재의 현황을 종합한 결과 외성의 보수정비를 진행할 경우 대체석으로는 화강암질편마암이 적절할 것으로 판단된다.
