Abstract
The analysis of structural features and operating conditions of the prefabricated reinforced concrete lining of a pressure hydraulic tunnel was carried out. The requirements to be met by the elements of the lining in question – tubing and anti-filtration seals in the longitudinal joints between the tubings are formulated. Features of determining loads and impacts on the tunnel lining in question during the construction, operational and repair periods are analyzed. Design diagrams that should be used to determine the stress-strain state of the lining in question during these periods are developed. A technique for calculating the stress-strain state of the system «lining – an array of rocks» is proposed. The criteria, which ensure the mechanical strength of the tubings and their joints, are formulated. The condition providing the design mode of operation of the anti-filtration elements in the longitudinal joints between the tubes is recorded. The results of calculations for justifying the design of prefabricated reinforced concrete lining of pressure derivation tunnel of Mtkvari HPP in Georgia, under construction at the moment, are presented.
