“…Landslides represent a large percentage of all domestic disasters, and damage from these events has been increasing. According to the Korea Forest Service, the damaged area and cost of restoration due to the landslide are increasing every year, and this increasing trend is clearly observed by calculating the cost of restoration compared to the damaged area (Choi et al, 2019). This is thought to be due to the concentration of human and material resources in the wake of industrialization and urbanization.…”

This study developed and verified landslide evacuation management criteria through the analysis of surface behaviors (the surface displacement and slope) to minimize casualties and property damage caused by landslides. First, for the surface-displacement–based evacuation management criteria, short-term–based management criteria were developed through the analysis of experimental results, and long-term–based evacuation management criteria were developed through the analysis of site collapse data. Furthermore, the reliability of the developed criteria was verified through additional experiments and comparison with the results of previous domestic and overseas studies. Next, surface-angle–based evacuation management criteria were developed through the analysis of experimental results, and the reliability of the developed criteria was verified through additional experiments. Finally, the phased management criteria of these two criteria categories were directly compared and their similar results (i.e., warning times) were verified. This analysis confirmed that the investigated surface-angle–based management criteria can serve as an auxiliary form of the surface-displacement–based evacuation management criteria.

This paper describes the Measurement Management Criteria (MMC) of a soil slope failure based on displacement using literature reviews, small-scale experiments, large-scale experiments, and field data. Two types of measurement management criteria were developed, i.e., short-term criteria for slopes under construction or requiring urgent measurements, and long-term criteria for slopes under continuous management. First, the measurement criteria for the short term were determined based on small- and-large scale experiments, and were determined to be “1 mm/min for the watch level,” “4 mm/min for the caution level,” and “21 mm/min for the alert level.” Next, the criteria for the long term were determined through a literature review and field data, and were “2 mm/day for the watch level,” “8 mm/day for the caution level,” and “56 mm/day for the alert level”.
