摘　　要：为了优化曲线型退水渠糙条消能工的导流效果,试验通过改变曲线型退水渠内糙条的布置型式,采用正交试验法分析糙条相对高度、糙条高度比、糙条间距、糙条角度、糙条厚度、糙条长度6个因素对曲线型退水渠水流导流效果的影响。结果表明,影响曲线型退水渠内糙条导流效果的因子重要性排序为:糙条角度>糙条高度比>糙条厚度>糙条长度>糙条相对高度>糙条间距;当糙条相对高度为1.70 m、糙条高度比为1.0、糙条间距为10.00 m、糙条角度为60°、糙条厚度为2.30 m、糙条长度为18.00 m时,曲线型退水渠水流的导流效果较无糙条工况提升了31.65%。In order to optimize the diversion effect of the rough-strip energy dissipator(R-SED)in the curvilinear drain channel,the orthogonal test method was used to analyze the influence of six factors,such as the relative height of R-SED,the height ratio of R-SED,the spacing of R-SED,the angle of R-SED,the thickness of R-SED and the length of R-SED on the flow diversion effect of the curvilinear drain.The results showed that the angle of R-SED and the height ratio of R-SED were major factors affecting the diversion effect.When the relative height of R-SED was 1.70 m,the height ratio of R-SED was 1.0,the spacing of R-SED was 10.00 m,the angle of R-SED was 60°,the thickness of R-SED was 2.30 m and the length of R-SED was 18.00 m,the diversion effect of curvilinear drainage channel was improved by 31.65%compared with the condition without R-SED.
