Three-dimensional Imaging of Dam Structure and its Application

Abstract With many high-hazard potential dams and long river embankments in China, the task of reinforcement of hydraulic projects needs tremendous efforts. Thus, it is of great significance to carry out effective structure quality control and hidden hazard detection. Based on GSR-3D imaging system and dam engineering practice in China, three-dimensional imaging system for dam structure with China's national conditions was created through secondary development. The system had already been applied in several reservoirs. And the application results show that the system can well realize real-time presenting in all material partition shape of dam and has a high imaging ability. Therefore, the three-dimensional imaging of dam structure provides complete real-time analysis and imaging tools for the internal structure and the orientation of hidden trouble of dams and embankments, which can be used for detecting construction quality and safety hazard, for experts to determine the security state of engineering and for leadership to make decisions by providing the scientific basis.
