摘要

The riverbed powerhouses of run-of-river hydroelectric power plants (HPPs) and the water-retaining powerhouses of pumped-storage power plants (PSPPs) are widely used and share structural similarities. One key component is water-retaining walls, which withstand hydraulic loads and transfer forces to floors and other structural elements of the building. Over prolonged operation, the upstream reinforced-concrete walls of turbine halls and shield walls may require strengthening, for example, with composite materials. Planned experimental studies will investigate reinforced-concrete models of wall and floor fragments of HPP and PSPP powerhouses, incorporating reinforcement with prestressed basalt fiber-reinforced polymer (BFRP) bars (two experiments have already been conducted), as well as carbon fiber-reinforced polymer (CFRP) tapes. Additionally, numerical simulations will be carried out using three-dimensional finite-element models of buildings.
