摘要
针对大坝原型监测具有监测项目与监测仪器众多、空间分布广以及需要对海量监测数据做出适时处理与分析等特点,基于GIS平台建立大坝监测仪器的空间信息与监测数据的有机联系,应用大坝安全监控理论对大坝原型监测资料进行分析与建模,探讨系统数据库设计与空间数据的表达、监测数据预测模型适应性等问题,并结合清江隔河岩大坝工程构建了基于GIS平台的大坝安全监控系统。应用结果表明,基于GIS平台的大坝安全监控系统具有良好的数据管理、监测数据分析和可视化显示等功能,可显著增强大坝安全监控分析的直观性,提高大坝安全监控数据分析的工作效率。
According to the characteristics of various monitoring items and instruments,complex distribution of monitoring instruments and real-time treatment and analysis of monitoring data in the prototype monitoring of dams, the relationship between the spatial information of monitoring instruments and the monitoring data was established based on GIS platform.The dam safety monitoring theory was applied to the modeling and analysis of the prototype monitoring data of dams.The design of the system database and the expression of spatial information and the adaptability of prediction models of the monitoring data were discussed.A dam safety monitoring system based on GIS platform was established as regards the practice of Geheyan Dam on Qingjiang River.The results show that the proposed system has satisfactory functions of data management,analysis of monitoring data,visual display and so on.It can significantly improve the visualization and efficiency of analyzing dam safety monitoring data.
