高混凝土面板堆石坝变形破坏机理与应对措施的新思考

Key Points

• This research aims to develop a comprehensive understanding of deformation mechanisms in high concrete faced rockfill dams for safety enhancement.
• Investigated deformation mechanisms of a 200m high concrete faced rockfill dam.
• Proposed a unified prediction method considering fill deformation, water storage deformation, and long-term creep.
• Introduced dual control criteria based on deformation prediction and coordination.
• Suggested using ultra-high strength concrete to enhance panel crack resistance and compression failure capacity.
• Proposed high-strength flexible impermeable composite materials to withstand high water pressure and large three-dimensional displacements.
• Introduced techniques to reduce dam deformation using added bonding materials to create reinforcement zones.
