Under the impact of many factors, the construction process of high core rock-fill dam is complex, so it＇s difficult for the whole process simulation to face dynamic construction process during the design process. Based on the detailed analysis of modeling method, construction dynamic simulation system for gravelly soil core rock-fill dam based on monitor and forecast information was built by using system simulation technology and database dynamic link technology etc. The analysis of the overall system development framework was focused on, and effect mechanism of monitor and forecast information to dynamic simulation system was proposed. Circulation process of monitor and forecast information in database and implementation model of each function module in system were given in a detailed description. The application results indicate that the simulation system is effective and rational by analysis of result contrast to traditional simulation, and provides effective technological support for the analysis and forecast of construction schedule of gravelly soil core rock-fill dam.
