3-D simulation of concrete placement progress of roller compacted concrete dam

With the development of the virtual reality technique,the 3-D simulation,as a management method with new perspective and a technical means,is playing an increasingly important role in the management of construction progress.The OSG(OpenSceneGraph)and QT framework based developing method of the simulation system for the concrete placement of dam is discussed herein.The system can generate the corresponding actual status of the concrete placement in accordance with the real construction elevation data.Based on the design with the method mentioned above,a 3-D simulation system for the concrete placement of a roller concrete dam has been already realized as well.
