This study examined soil parameters, existence of ground water, and the safety factors of slope according to the ground water level. The following are the conclusions of the study. (1) The safety factor became less as the ground water level decreased. (2) The greater the cohesion became, the less the safety factors according to the ground water level did. (3) In the case with ground water, greater cohesion had less effect on the safety factor. However, in the case without ground water, changes in cohesion had considerable effects on the safety factor. (4) While the safety factor increased associated with increase in the angle of shear resistance as the ground water level, the safety factor according to cohesion was almost constant.
