Study on 3-D visual dynamic simulation system for construction of roller-compacted dam

The construction process of the roller-compacted dam (RCD) is discussed from the point of view of the system simulation and visualization herein, and then a 3-D visual dynamic simulation system of RCD construction is developed. Based on VC~(++), and combined with the technique of database, the system realizes the simulation of the construction process with the relevant simulation assumption of the specific problems such as zoning and dynamic binding of the concrete placing blocks etc. After the 3-D modeling, the 3-D dynamic raising process of RCD concrete placement can be displayed with the geographic information system. Finally, the simulation system is applied to a practical project, with which a good basis is made for the decision-making of the construction management concerned.
