Advancing Road Cut Slope Stability in Nepal
Keywords:
Roads, Slope stability, Landslides, DesignAbstract
Road cut slope failures (a type of landslide) are extensive across Nepal’s road network. This study implements a multidisciplinary approach (including participatory approach methods, geotechnical, geomorphological, geological fieldwork, and geotechnical numerical analyses) to assess the stability of road cut slopes across Nepal, to improve their stability through advanced design guidance for local roads. Here, we present an overview of this multidisciplinary approach.
