摘要： 本文根据特征理论将圣维南方程组化为黎曼方程,据此求得平底无阻力无限长棱柱体U形河槽溃坝波的简化解,其成果可用作估算最大溃坝流量,坝址水深及波及区域内的瞬时水面线。

Abstract: According to characteristic theory, Saint-Vinant equations are reduced to Riemann equations.In this way, we found the simplified solution of dam-breaking wave in U cross-section channels, assuming both bed-slope and the friction slope to be zeros. When the initial depth of the reservoir h1 is given, water depth at dam-side, maxima of discharge, and water surface profile before occurence of the reflected wave can be predicted.
