二次开发的GSR-3D大坝结构三维成像系统及应用

Dam Structure Imaging System Based on Secondary Development of GSR-3D and Its Application

针对我国大坝隐患探测常用技术受环境影响大、工作效率低、无图形用户界面、无完善的前后处理功能的问题,结合我国大坝工程实际,将GSR-3D成像系统进行了二次开发,建立了符合我国国情的大坝结构三维成像系统,并在实际水库中进行了效果验证。结果表明,该系统能较好地实时呈现大坝各材料分区形状,同时对大坝结构三维成像效果较好,可为病险水库大坝内部结构、工程隐患定位提供完整的实时分析与成像手段,可用于快速检测建筑质量及安全隐患。

According to the common technology of dam hidden trouble detection in China with environmental-impact disadvantage, low working efficiency, no graphical user interface, no perfect pre-process and post-process functions, based on the dam engineering practice in China, three-dimensional imaging system of dam structure with China＇s national conditions is established by using the secondary development of GSR-3D imaging system. The system has been applied in several reservoirs. The application results show that the system can well realize real-time presenting in material partition shape of dam and has good three-dimensional imaging effect of dam structure. Therefore, the system provides complete real-time analysis and imaging tools for internal structure of dangerous dams and the orientation of hidden trouble, which can be used for detecting construction quality and safety hazard.
