Abstract

A Case Study on the Stability and Reinforcement Method of Slope with Soil Lee, Suok Advisor : Prof. Kim, Daehyeon Department of Civil Engineering Graduate School of Chosun University In the process of development of the national land, the utilization of mountains and hills is incresed. In this case, the stability of a natural slope problem has been investigated. Recently, due to changes of the summer weather pattern, damage caused by debris flows is occurring in the mountainous area frequently. In this thesis, a case study on reinforcement for a failed cut slope is introduced. An extensive field investigations and analyses were performed and the most effective way of stabilizing the slope was suggested. When the soil-nailing is applied to the upper part of the slope, constructability, economical efficiency and stability are satisfactory, and safety factors of dry season and rainy season are satisfactory. This study could be a good example for similar situations in which a natural slope failure occurred.
