Optimization Of Steel Penstock In A
Bored Tunnel
Author(s)
S. Kravanja
Abstract
This paper presents the optimization of steel penstock, designed to be built in a
bored tunnel. The optimization was performed by the non-linear programming
(NLP) approach. For this purpose, the NLP optimization model was developed.
The model comprises the mass objective function, which is subjected to design
and dimensioning constraints. The dimensioning constraints were defined
according to C.E.C.T. recommendations. The penstock was designed without
stiffener rings and without collaboration of the surrounding rock. Numerical
example of the penstock optimization, planned to be made for the hydropower
plant Kozjak in Slovenia, demonstrates the efficiency of the introduced
optimization approach.
Keywords: steel penstock, steel liner, bored tunnel, optimization, non-linear
programming, NLP.
