초록
Landslides triggered by rainfall produces severe effects on the serviceability and stability of railway operation. Since small amount of soil mass slipped on the rail can cause derailment which will cause severe danger on the human and trains, slope stability problem is one of the major concerns on the operation of railway. In this study we investigate the some of characteristics of rainfall driven landslide near railroad. A total of 23 sites were visited. From the results four types of landslides based upon the morphology of the slipped slope triggered by rainfall were classified. From the analysis dimensions of slopes (height, length and slope) do not show particular correlation with the types of landslides. In addition, morphological and geological features of slope influence on the occurrence of different types of landslides.
