Construction Technology for Mass Concrete Bearing Platforms in Deep Foundation Pits

This commentary proposes an optimized integrated construction technology system for the mass concrete bearing platform of cable-stayed bridge main piers in complex geological deep foundation pits, alongside targeted quality and safety control measures validated by on-site data. The technology effectively resolves hole collapse in silty fine sand and mass concrete crack control, realizing 100% concrete strength qualification and compliant structural integrity. Its core contribution is a reliable, adaptable technical solution for this engineering scenario, offering practical references for similar projects, and laying a foundation for relevant technological optimization while indicating the need for expanding technical adaptability in follow-up research and the application potential of intelligent construction technologies.
