In order to fully understand the advantages of rock-filled concrete with low cement content and friendly envi-ronment,the construction of large bin surface pouring is verified by increasing the spacing of transverse joints.Based on the rockfill concrete gravity dam of Shibahe Reservoir in Guizhou Province and the engineering design data,construction technology and temperature monitoring results of the whole process,the overall safety of the dam structure is evaluated through analysis of the thermodynamic properties of dam construction materials and the simulation calculation of the work-ing behavior of the dam during construction.Through the feedback of the initial water storage operation and safety moni-toring,the seepage prevention and overall safety of the dam can be guaranteed,which indicates that the large bin surface pouring method of rockfill concrete is feasible.The integrated pouring method of large bin surface of rockfill concrete is beneficial to reducing construction interference,speeding up construction progress and reducing hydration heat tempera-ture rise,and has significant economic benefits,which could provide good reference for similar projects.
