Analysis of landcreep according to Korea’s landslide risk assessment criteria

抄録

This study was conducted to establish basic data for calculating the risk grade of land push in the future by comparing and analyzing landslide disasters and land push that generally occur using the landslide risk determination standard table. Among the factors influencing 57 landcreep areas nationwide, slope length, slope location, clinical, slope type, soil depth, slope, etc. were selected and classified according to the landslide risk determination standard table, and then correlation between slope type and rock was significant at 5%. Excluding this, there were statistically insignificant results among factors, and judging by these results, it is considered that the landslide risk determination standard table is not suitable for applying to the ground push. Of the 57 landcreep sites in Korea, 35 areas (about 61.4%) are unlikely to have landslides or are not likely to have landslides, making it difficult to accurately determine if landcreep is judged as a landslide risk determination standard. In 57 land forests, the largest number of areas were classified as areas other than landslide risk grades that were not included in landslide risk grades 1 to 5, indicating that many areas were not included in the landslide risk grade.
