英文摘要：
Construction simulation of rockfill dam with asphalt concrete core （RDWACC） is an advanced technology. It takes advantage of computer simulation to observe and analyze a complex construction operation, It provides a use- ful tool for construction design and management. The decomposition and coordination of RDWACC＇s construction system were carried out, and then the basic theory of construction simulation for RDWACC was described. Consider- ing the complex constraints of construction process, the mathematical logic relation model of construction dynamic simulation of RDWACC was built. Based on the Unity3D engine, the 3D visual analysis system for RDWACC con- struction under network environment was developed. The research achievements were applied to a practical project, and the results show the efficiency of the simulation models and the advancement of the technical method.
