Abstract
The road slope at Hapcheon-Gun, Gyeongsangnam-Do is under construction, but actual rock quality & discontinuities on the cut slope are something different from the primary design. Therefore, object of this study is to analyze whole engineering-geological characteristics for this slope through site investigation and laboratory analyses because small scale landslides have been occurred during this road construction. For this object, various analyses were performed such as surveying, Schimidt Hammer test, discontinuity investigation and laboratory analysis using DIPS far evaluating slope stability. As the result, it is identified that reinforcement work is needed because plane, toppling & wedge failures will be possibly occurred and seepages are concentrated at several points.
