Rock mechanics in the investigation and construction of Tumut 1 Underground Power Station, Snowy Mountains, Australia
(a) Alternative arrangement of the power station with parallel machine
hall and transformer hall. Model is under vertical compression, with
no lateral restraint.
(b) Stress concentrating effect of a V-notch gelatine
model, with side pressure approximately equal to the vertical stress
due to gravity. Side pressure applied by means of flexible bags filled
with liquid of the same density as the gelatine.
