摘　　要：通过模型试验 ,进一步揭示了急流弯道中 Fr1和 r0 / B对θ及 h2 / h1的影响 ,提出了防止弯道出现干底现象的界限 。By means of model experiment, the influences of Fr 1 and r 0/B under supercritical flow in curved channel on θ and h 2/h 1 is further studied, the limiting value of preventing the occurrence dry bottom in the bends is provided, and the empirical formula of wave angle β 1 is presented.
