Operational Mechanism of a Novel Permeable Reinforced Concrete Lining in High-pressure Tunnels
摘要
Abstract
With the rapid development of pumped-storage power stations,reinforced concrete linings in high-head water conveyance tunnels are confronted with challenges such as a high risk of cracking,difficulties in monitoring crack propagation,and unclear operational mechanisms after cracking.To address these challenges,this study proposes a novel permeable reinforced concrete lining structure designed to achieve controllable crack initiation locations and effectively monitor crack propagation.At the same time,a pore-fracture seepage-stress coupled mechanical model and corresponding numerical method are established,and the working mechanism of the proposed structure in high-pressure tunnels is investigated by combining 3DEC discrete element numerical simulation with engineering case studies.The results show that the structure can dynamically reflect crack width variations,internal water seepage processes,and structural stress states,while fully utilizing the load-bearing capacity of the surrounding rock.The structure also exhibits superior mechanical performance,controllable cracking,and convenient monitoring,making it suitable for high-head pressure tunnel engineering.关键词
