This dataset contains the numerical calculation results of the filling and water storage of the core wall rockfill dam of Rumei Hydropower Station, including finite element model data, as well as the calculation results of axial horizontal displacement, horizontal displacement along the river, vertical displacement, pressure head, pore head, large principal stress and small principal stress of the dam. The folder title is the corresponding construction period.
In this dataset, there are two files: "DamStatic 01. txt" and "DamStatic 02. txt". "DamStatic 01. txt" includes: axial coordinates of the dam (m), coordinates along the river (m), vertical coordinates (m), horizontal displacement along the dam axis (m), horizontal displacement along the river (m), vertical displacement (m), pressure head (m), and total head (m); DamStatic 02. txt "includes: axial coordinates of the dam (m), coordinates along the river (m), vertical coordinates (m), horizontal displacement of the dam axis (m), stress in the X-X direction (kPa), Y-Y direction (kPa), Z-Z direction (kPa), X-Y direction (kPa), X-Z direction (kPa), Y-Z direction (kPa), first principal stress (kPa), second principal stress (kPa), third principal stress (kPa), and stress level.
This data was calculated using the "High Earth Rock Dam Stress Deformation and Disease Disaster Process Simulation Software" independently developed by the Geotechnical Institute of Nanjing Water Resources Research Institute.
Based on the collected material parameters of various areas of the Meixin Wall Dam, the Duncan Zhang E-B model was modified for parameter calibration, and based on this, stress and deformation calculations and analysis of the dam body were carried out for filling, water storage, and emptying.

The calculation results show that the settlement measurement values of various parts of the core wall axis gradually increase with time, and overall show a general pattern of fast growth in the early stage and slow development in the later stage. The settlement pattern is consistent with engineering experience, and the numerical analysis of settlement pattern is consistent with the feasibility study report, which can better predict the distribution of settlement along the core wall axis in Rumei Dam.
