A dynamic control model for construction progress of the storehouse surface of core rockfill dams is proposed based on thesimulation model for construction progress and thereal-time monitoring model for construction quality of the storehouse surface, with field construction factors taken into consideration. Through optimization of the construction scheme and real-time analysis and feedback of progress deviation during the construction process with the model, the construction progress control before and during the construction process was realized. The model was applied to a core rockfill dam under construction. An optimized scheme for advance control of construction progress of a storehouse surface was chosen based on optimization and simulation analysis of multiple construction schemes. When the construction progress was stunted by unforeseen circumstances, the simulation model for storehouse surface construction was used to dynamically simulate and update the construction situation, and an optimized scheme for intermediate control of construction progress wasrecommended. The schedule of storehouse surface construction can thus be guaranteed. The application results showed that the actual construction scheme was consistent with the chosen one, only with a deviation of 23 minutes in the construction process. Therefore, the storehouse surface construction progress could be effectively controlled with the dynamic control model. As conclusions, the model can provide a reasonable and optimized construction scheme, effectively control the deviation in construction progress, and guarantee the construction progress of a storehouse surface of core rockfill dams.
