Abstract
Varahi river in Karnataka State, India originates on the Western Ghats and is harnessed for power generation by constructing three dams. The water is conveyed through two inclined pressure shaft to the underground power house below the Ghats. The underground power house of the Varahi Hydro Electric Project executed by the Karnataka Power Corporation has 2 units of 135 MW each in the first stage with a provision to add two more identical units. Three underground cavities are excavated parallel to one another for housing the rotary valves, generators and the transformers respectively and are at a gee-static head of about 230 m. The paper deals with a case history of the excavation practice and the stabilisation measures adopted during the excavation of the cavities for housing the underground power house complex of the Varahi Hydro Electric Project in Karnataka, India.

Geotechnical Problems Encountered During the Excavation of Underground Cavities for Varahi Hydro Electric Project
St. Louis, Missouri
Varahi river in Karnataka State, India originates on the Western Ghats and is harnessed for power generation by constructing three dams. The water is conveyed through two inclined pressure shaft to the underground power house below the Ghats. The underground power house of the Varahi Hydro Electric Project executed by the Karnataka Power Corporation has 2 units of 135 MW each in the first stage with a provision to add two more identical units. Three underground cavities are excavated parallel to one another for housing the rotary valves, generators and the transformers respectively and are at a gee-static head of about 230 m.
