Based on the permanent slope project of TBM starting platform of water diversion tunnel of a hydropower project in Nepal,this paper introduces the design scheme and construction key technologies of soft rock high slope under the condition of Siwalik geological region.Through stability calculation,soil nail bolt+grid beam/spray anchor support+comprehensive drainage measures are adopted.Through construction monitoring combined with permanent monitoring data analysis,the overall stability of the slope is achieved,meeting the design requirements.
