This article uses the developed \"High Earth Rock Dam Stress Deformation and Disease Disaster Process Simulation Software\" to invert and calibrate the modified South Water Double Yield Surface elastoplastic model, wetting model, and rheological model of the main dam materials using monitoring data during the filling period, water storage period, and operation period, respectively. Based on this, deformation calculation and analysis during long-term operation were carried out.\n
The calculation results show that the long-term deformation of the dam body conforms to the deformation law of the core wall rockfill dam. The maximum settlement calculation and monitoring values are 4.94 m and 4.78 m, respectively, with a relative error of 3.5%.
