Abstract

Based on the prominent type of failure, the highway (Mugling–Narayanghat road section in Nepal) can be divided into 3 sections : a) dominated by shallow landslides and debris slides/flows; b) dominated by large-scale, deep-seated landslides; and c) dominated by rock topples. According to the selected methodological approaches, data from detailed geological, geomorphological and geomechanical surveys, it is clear that these topples are mainly related to the geological structures of the region. Additionally, the landslide contains several sheared zones where the rocks are considerably weathered. These sheared zones act as the sliding plane. Also, the debris fan at the lower part suggests that the landslide has been reactivated several times in the past. Furthermore, it is seen that flexural toppling occurs in weak, mica-rich slate/phyllite at the upper slope, while block toppling is prominent in stronger amphibolites and quartzite lying in the central par
