摘要
为了解决堤防隐患探测过程中存在的测线布置工作效率低、二维图像解译结果无法有效表达隐患或异常等问题,基于三维地理信息服务平台建立了堤段三维模型及堤防周边的三维地形模型,并建设了堤防隐患工程地球物理探测数据库,研发了一套堤防隐患探测分析系统,并开发了地球物理多方法与平台的数据接口、数据库存储及物探成果四维可视化表达方法。结果表明:该模型可实现地球物理野外工作路线和观测系统的快速布置和设计;该模型和数据库可实现堤防时移探测成果的四维可视化表达、动态分析及管理。研究成果可供从事堤防隐患治理的管理人员及设计人员参考。
In detecting hidden dangers of dyke,the configuration of survey line is ineffective,and the interpretation result of 2D images could hardly describe hidden dangers or anomalies effectively.In view of this,the 3D model of dyke segment and the 3D terrain model around the dyke are established based on the 3D geographic information service platform.The geophysical prospecting database for hidden dangers of dyke is established,and a detection and analysis system is developed.Moreover,the data interface,database storage and 4D visualization expression of geophysical prospecting results are developed.In conclusion,the 4D visualization expression,dynamic analysis and management of time-lapse dyke detection results are realized.
