摘　　要：基于Delphi应用软件及Surfer接口技术实现大坝等值线的自动绘制,既发挥Delphi数据库功能强大、开发效率高等优点,又充分利用了Surfer卓越的网格化和绘图能力,减少了绘制等值线图的手工劳动,从而大幅度节约了批量绘制等值线图的时间,提高了工作效率。实际应用表明,在大坝安全监控系统中采用该技术,能够方便、快速、准确地绘制大量的等值线,为大坝安全分析提供了及时有效的工具,因此具有良好的应用前景。A technique for interfacing between Delphi and Surfer, which combines the virtues of the powerful database and high development efficiency of Delphi and the superexcellent gridding and mapping ability of Sufer, is used to realize the automatic drawing of dam isolines. It economizes the manual labor and work time of isoline drawing, and improves the work efficiency. Practical application shows that this technique can draw a lot of isolines conveniently, quickly and accurately when used in dam safety monitoring systews. The technique provides a timely and effective instrument for dam safety analysis, and has good application prospects.
