Concrete dam construction management and decision-making platform is established based on virtual reality. In the platform, the multi-dimensional construction information is integrated highly, including dam constructure, pouring bins, construction schedule, construction machines, construction site management and so on. Virtual construction scene is shown lively in the platform. The construction progress and construction field can be managed real-timely and interactively in the platform. The platform provides a completely new environment for concrete dam construction management and decision-making. The platform has rich functions on concrete dam construction management and decision-making, such as construction information management, dam model editing, pouring bins management, construction scene roaming, construction animation rendering, construction schedule simulation, construction machine operation, construction progress interaction.
