Abstract

Various geological structures are found on the slope of Bangnim district in Pyeongchang, Gangwon-do, based on the Paleozoic Joseon Supergroup Limestone. The recumbent fold observed on the slope is a very rare geological structure that has not been found in Korea, and has important academic value in exploring the formation process of the Paleozoic geological structures in the Gangwon region. In this study, discussed the geological value of the geological structure observed on the slope of the road, and studied the management method of rockfall problem slopes. The state of development of recumbent folds has conservation value in geological scarcity and specificity. Preservation management measures should be prepared through the protection of slopes and measures to reduce of rockfall risks as geoheritage with an important value in geology science and education. Furthermore, it is expected to be preserved and utilized as a geopark.

강원도 평창 방림 지구 깎기 비탈면에 드러난 단면은 고생대 조선누층군 석회암층을 기반으로 다양한 지질구조가 발견된다. 비탈면에서 관찰되는 횡와습곡(recumbent fold)은 우리나라에서도 발견된바 거의 없는 매우 희귀한 지질구조로 강원도 지역 고생대 시대의 지질 구조의 형성과정을 규명함에 중요한 학술적 가치를 지니고 있다. 본 연구에서는 도로비탈면에서 관찰되는 지질구조의 지질학적 가치에 대하여 논의하며, 위험비탈면의 관리방안을 위한 연구를 수행하였다. 본 횡와습곡의 발달 상태는 지질학적 희소성, 특이성 등에서 보존가치를 지니고 있으며 지질과학 교육적 중요한 가치를 지니는 지질유산으로써의 보호 및 낙석위험 저감대책을 통한 보존 관리방안이 마련되어야 하며 나아가 지질공원(geopark)으로 보전되고 활용할 수 있을 것으로 기대된다.
