Abstract
Infiltration characteristics of cut-slope safety factors are considered for precipitation duration and intensity. Infiltration characteristics (infiltration module) and safety factor (slope module) changes of a cut-slope are analyzed under various conditions of precipitation intensity and duration, using the Soilworks program. The results indicate that the addition safety factors of the slope decreased immediately after the end of precipitation due to an increase in pore water pressure. The minimum safety factor for cut-slope infiltration analysis should be considered because of the because of the decrement of safety factors after precipitation that exceeds the decrement of safety factor during the duration of precipitation.
