中文摘要：
为了从整体上了解坝体位移规律，提高监测资料的分析效率，借助Delphi开发环境，提出了一种运用TChart控件来实现大坝三维位移场可视化以及交互操作的有效手段．即将大坝位移测点及监测数据构成的体数据，以等参单元形函数插值生成坝体位移的3D规则数据场，再根据位移值大小赋予相应部分的颜色并设置Chart和Series相关属性，继而调用TChart的相应图件进行图像的绘制与编辑、结合某坝实测数据，将这些方法与技术集成实现，取得了良好效果，说明了TChart控件在大坝位移场可视化技术研究中的有效性．
英文摘要：
In order to understand the entire law of dam displacement and improve the analysis efficiency of monitoring data, a TChart-based technique in Delphi that realizes the visualization of the 3-D displacement field of the dam and includes the interactive operation is described in detail. First, according to the volume data consistant with the coordinates and monitoring data from dam displacement measurement points, the 3-D regular data field of dam displacement is generated by shape function interpolation of the isoparametric element. Then, based on the displacement values, the corresponding parts are endowed with colors, and the relevant attributes of the Chart and Series are set. Finally, the corresponding maps of TChart are called for drawing and editing images. The methods and techniques are applied to an arch dam and good results are obtained. This shows that the TChart component is effective in the visualization of the 3-D displacement field of the dam.
