摘　　要：基于大坝安全自动化监测系统实测数据,采用矢量-栅格混合模型进行二三维数据的结构转换,并以空间数据管理引擎与对象关系数据库相结合的方式对多维异构数据集成管理;进而形成场景模型建立流程和监测信息三维可视化方法,实现大坝安全监测三维可视化实施方案并进行应用。研究成果能够兼顾大坝安全监测二维和三维信息的优势,提高多维信息存储与管理效率,进一步提升监测信息的直观性和实时性。Based on the measured data of dam safety automatic monitoring system, by using the vector and raster mixed model for the structure of the 2-3D data conversion, it does multi-dimensional heterogeneous data integration management which is through the method of combination for spatial data management and object relational database engine. Through the formation of 3D scene modeling process and monitoring information visualization methods, it realizes scheme of 3D visualization for dam safety monitoring and has been applied. Research results can give attention to both the advantage of 2D and 3D information for dam safety monitoring, improve the efficiency of multi-dimensional information storage and management, further enhance the visual and real-time of the monitoring information.
