Current status and development trends of adit excavation technology in hydropower engineering

Abstract:

This paper comprehensively examines the current status and development trends of tunnel excavation technology in hydropower projects. First， it introduces the definition， functions， and significance of exploration adit in hydropower projects. Subsequently， it provides a detailed analysis of the technical characteristics， application scope， advantages， and limitations of traditional drill-and-blast methods， mechanical excavation methods， and emerging tunneling technologies. The paper also discusses the major challenges faced by current tunnel excavation techniques， including complex geological conditions， environmental protection requirements， and concerns regarding construction efficiency and safety. Finally， it outlines future development trends， such as the application of intelligent and automated technologies， as well as green and environmentally friendly techniques. This study aims to serve as a reference and guide for the further advancement of tunnel excavation technology in hydropower projects exploration.
