건기 조건의 사면 안정 해석과 관련된 문제점 고찰 및 대안

초록

Safety factors used in slope design is divided into wet and dry condition. In general, a safety factor of 1.5 is used for the dry condition and 1.2~1.3 is used for the wet condition. Unfortunately the application of safety factor for the wet and dry condition for the same slope has some problems. Slope stability analysis programs were used to determine problems in the slope design conditions. Stability analysis were performed and reinforcements to calculate safety factor for the wet and dry condition of arbitrary slope. Slope designed conditions used in Korea and other countries were analyzed and compared. When slope stability analysis for the wet and dry condition is performed separately, it was determined from the result of the study that the safety factor for the dry condition is always satisfied when the safety factor for the wet condition is satisfied. This shows that there is a problem in the condition of stability analysis that is currently used and modifications must be made except the dry conditions analysis.
