침투를 고려한 사면안정과 보강에 따른 안정성비교 = Soil Slope Stability Analysis Design Considering Infiltration and estimation for the safety factor based on reinforcement

다국어 초록 (Multilingual Abstract)

Most slope failure occurs due to heavy rainfall during rainy season. For rainfall duration in the season, the safety factor of soil slope gets lower because the water content of the ground increases and the matric suction of that decrease. The change of water table level at the slope almost does not affect on the safety factor of a slope and then, it also may be necessary to modify the design standard for slope stability. In order to secure design, construction, and maintenance of a soil slope, the slope instability needs to estimate rainfall infiltration and soil behavior on unsaturated soils. The entire soil slope can not be saturated by prolonged rainfall and the saturated zone just deepened at slope surface due to it. Hence the shallow slip surface occurs depending on the influence of rainfall duration and intensity. The paper presents the differences between theoretical equation and numerical analysis for saturated depth on soil surface and the safety factor, and the slope stability obtained from infiltration analysis on unsaturated soil compares with that obtained from conventional slope stability analysis.
