This study examined a case of collapse and reinforcement of the colluvial deposit slope in Kyeongnam Geoje Area. The reason for the collapse was found first in the reduction of the resistant force due to slope-cut for constructing retaining walls. This decreased the resistant force against sliding, which enabled precipitation during the rainy period to seep into the ground in the upper colluvium, resulting in increase in porewater pressure. This leads to decreased shear strength and increased sliding force, which ultimately caused the collapse of the slope. For the long-term stability, methods attained for stability reinforcement are summarized in the following table.
