FEATURES OF REINFORCEMENT OF CONCRETE-ENCASED STEEL PENSTOCKS

Cover Page

Abstract


Concrete-encased steel penstocks that lead the water to the hydroelectric units of the Hy- dropower Plants (HPP or PSPP) include internal steel shell and a reinforced concrete shell. Within the areas of compensation on track adjacent structures through which the penstocks passes, internal steel shell separated from the reinforced concrete shell by low-modulus spacer. Existing regulatory documents do not provide specific guidance on the calculated defi- nition of reinforcement of compensatory plots of penstocks. The technique destination of the reinforcement (with the development of reinforcement scheme) of the compensatory plots on the basis of numerical modeling of the stress-strain state of concrete-encased steel penstocks is proposed.
