溢流坝堰面曲线的简捷计算与绘制

Simplified Calculation and Mapping of Weir Surface Curve of Overflow Dam

溢流重力坝设计和施工时需要计算并绘制堰面曲线及堰剖面图,关于堰顶为克-奥曲线的堰面曲线的连接计算已有文献介绍过,而关于堰顶为WES曲线的连接计算已有文献介绍,但繁琐且不够准确。据此,文章介绍堰顶为WES曲线的堰面曲线的计算与绘制,此方法比现有的各种方法都直接、方便、简单、准确。

The weir surface curve and weir section shall be calculated and mapped when the overflow gravity dam is designed and construc- ted. Calculation on connection of the weir surface curves is available when the weir top is of the CO curve. The connection calculation is also available when the weir top is of the WES curve but it is complicated and inaccurate. Therefore, calculation and mapping of the weir surface curve are introduced in this paper when the weir top is of the WES curve. This method is direct, convenient, simple and accurate than other calculation methods.
