中文摘要：
为全面准确地掌握大坝监测数据的时空分布规律,利用可视化技术,首先提取坝体轮廓、测点及测值信息并进行维度分类,然后将信息进行时空插值连续化处理,空间上以色彩、距离表现信息,时间上不断更新,最终形成多维空间的信息可视化场量.应用结果表明,此方法能更直观地表现坝体信息的时空状态,便于观察、浏览和理解信息,发现大坝监测数据隐藏的规律和模式,可为坝体运行状况和结构寿命的分析评判提供形象的依据.
英文摘要：
The complete and accurate grasp of space-time distribution rules of dam monitoring data is the important perquisite to correctly evaluate the structural safety of dams. By use of the visualization technology,firstly,the information of dam contours,measuring points and values was collected and dimensionally classified. Then,the information was spatially and temporally interpolated. The color and distance were employed for the spatial information,and the time was continuously updated. Finally,multi-dimensional space visualization field of the information was generated. The applications show that the present method can more directly exhibit the space-time information of dams,and it is convenient to the observation,view and understanding of the information and to finding the hidden rules and patterns in dam monitoring data. It will provide a visual basis for the analysis and evaluation of operation situation and structural life of dams.
