Abstract: If the curve equation is not given for the upstreamcomplex- arc segment of practical curve- shaped dyke on its Ogee section, this may cause disadvantages in designing, construction control and project acceptance. By using the deductive curve equation in the paper, as the designed amount of gross water is definite, correspondingly the curve equation in the upstream complex- arc segment of practical curve- shaped dyke on its Ogee section could be gotten.

摘要： 由于曲线型实用堰渥奇(Ogee) 剖面上游复合圆弧段未给出曲线方程, 给设计、施工控制及竣工验收带来诸多不便。利用本文推导的曲线方程, 设计总水头一定, 即可得到相应的曲线型实用堰渥奇(Ogee) 剖面上游复合圆弧段的曲线方程。
