... concrete lining for those parts of the tunnels, which will be used as tailrace tunnels are underway. The present paper describes the present conditions of diversion tunnels No. 1 & 2 and explains the procedure used for stress analyses of tailrace tunnel No. 1 without and with the new lining, which, has...

... consists of a 2.81 km long concrete lined 7.5 m diameter horseshoe section headrace tunnel leading to a 58.0 m high surge shaft of 18.0 m diameter. Pressure shaft of 6.4 m diameter takes off from the surge shaft and is designed for a maximum discharge of 185.0 cumecs, 6.4 m diameter pressure shaft...

... shafts. The increased rock mass cover and therefore higher in-situ stress magnitudes (e.g. decreasing risk for hydro-fracturing) may allow unlined solutions instead of cost intensive steel lining (providing that water losses are economically acceptable). Both, concrete lining and rock mass are subjected...

... construction, the authors built the relationship among the initial deformation rate, the final deformation and stress of concrete lining as one of the practical guides of shaft sinking. It consists of four categories, Class I S , to IV S , and is useful to predict the rock mass behavior and stress of lining...
