Study of Dynamic Three-dimensional Visual Simulation for Concrete Faced Rock-fill Dam Construction

Concrete faced rock-fill dam of Hekoucun Reservoir has some futures, such as huge construction quantities, high filling rate, many construction influence factors and complicated construction organization design. The simulation calculation model is established by using dynamic stochastic cycle network, scanning clock value of the dominant entity, dynamic boundary constraints method. And then the real-time dynamic construction system of concrete faced rock-fill dam is simulated. At the same time, three-dimensional real-time appearance of the engineering is rendered with OGRE engine. The construction parameters of traffic density, filling rate, mechanical configuration and project progress are obtained. Finally, three-dimensional visual simulation is realized. The results provide data support for construction organization design and it can be as the basis for engineering decision-making.
