Excavation of a double-track tunnel from an existing triple-track alignment, incorporating a pilot tunnel in between and lateral slashing on both sides

Excavation start for Cross Passage in the tunnel.

This tunnel face, situated in the grouting gallery of the main dam foundation at an elevation of 286 meters above sea level and approximately 25 meters below from the river level, exhibits significant geological and geotechnical features. The rock type is Dolomite. From the perspective of a geologist and geotechnical engineer, what are your observations from this photograph? #Tanahu_Hydropower_Project_140MW #Dam_Foundation_Grouting_Gallery_Curtain_Grouting

Stabilizing the depths, Rock bolting is a critical process in tunnel construction, and this work required expert who can do it with precision and care. #tunnelconstruction #rockbolting #geotechnical #engineeringgeology

Dolomite can significantly affect tunnel stability. Its properties, such as porosity and water absorption, influence the design and construction strategies for tunnels. Understanding dolomite's behavior under stress and its interaction with water is crucial for ensuring the structural integrity and longevity of tunnels.

The mystery in geological mapping is that you never know what to expect after every blast round. Tunnel construction is proving to be quite interesting. Although I’m mapping basalt every day, today’s excavation face can differ tremendously from yesterday’s face. #LHDA_Phase_2 #Tunnel_Stability
