【摘要】 急流滩的水面线计算中,滩段阻力系数确定是计算的关键。通过理论分析提出了新的局部阻力系数经验公式,利用水槽实验资料确定了公式中的系数。经实际滩段的水面线验算,计算精度基本满足航道整治初步设计要求。更多还原

【Abstract】 Determination of the resistance factor is pivotal in calculation of water surface profile of rapids reach.A new kind of empirical equation for determining local resistance factor was set forth based on theoretical analysis,the coefficients in which were obtained by flume test.Checked by practical rapids reach,the calculation accuracy is proved to satisfy the preliminary design of channel regulation on the whole.更多还原
