초록
본 연구는 집중호우로 인하여 임도사면의 붕괴가 발생된 변성암지역 및 화성암지역의 임도를 대상으로 성토사면의 토질역학적 특성파악과 사면안정해석을 실시하였다. 그 결과는 다음과 같다. 1) 통일분류법에 의한 임도성토사면의 토질의 분류는 화성암과 변성암지역 모두 토사사면은 SW, 풍화암사면은 SP, 연암사면은 GP로 나타났으나, 호박돌 섞인 토사사면에서는 화성암지역은 SP, 변성암지역은 GW로 나다났다. 2) 화성암지역의 성토사면 흙의 건조말도는
This study was carried out to analyze the mechanical properties of soil and the slope stability on the fill slope of forest road constructed in the regions which consist of igneous and metamorphic rock area. The results were summarized as follows. 1) Soil type by Unified Soil Classification System(USCS) was classified as SW in soil slope, GP in weathered rock slope, GP in soft rock slope for both types of parent rock, but gravelly soil slopes in igneous and metamorphic rock area were classified as SP and GW, respectively. 2) Dry unit weight was
