高土石坝龙抬头泄洪洞抗蚀体型研究

本文通过理论分析，提出了一条曲率沿程处处连续的连续曲线，代替工程中常用的单圆弧反弧曲线，可改善反弧末端的压力分布，提高反弧的抗蚀性能，并以一种简单可靠的数值计算方法———流线迭代法。

Based on theoretical analysis, a new type curve with gradually variable curvature was suggested to substitute the circular curve which is often used in the design of flood tunnel. The pressure distribution on the curve surface is improved to prevent from cavitation erosion.
