摘要：
This paper describes the Nagdhunga Tunnel project, Nepal's first conventional excavation road tunnel. The tunnel located near the boundary where the Indian Plate subducts into the Eurasian Plate. The geology was complex, with many faults in metamorphic rocks such as phyllite and metamorphic sandstone and alternating permeable and impermeable layers. The design results based on the geological investigation and the current construction status are shown below.
