摘　　要：以位于金沙江上的溪洛渡水电工程为载体,对其泄洪洞出口进行了体型优化。利用椭圆弧的曲率特性,给出了泄洪洞出口椭圆弧体型的设计方法。成功地解决了原设计方案水舌挑距过短,淘刷本岸的缺点;同时克服了挑坎曲率突变、参数选择困难的弊端。文中给出的体型既可保证水体受力的均匀,又可适应不同工程的具体要求,可供溪洛渡工程及类似工程参考使用。Based on Xiluodu project on Jinshajiang River, the form of the body of the spillway tunnel is optimized in this paper. In order to solve the problem that the trajectory distance of the former type was too short to cause the scouring of the nearer bank, the elliptic arc soleplate is successfully applied in this project by using the curvature characteristics of elliptic arc. At the meantime, the parameters of the elliptic arc are also given in the paper, which can suit to the same project.
