| 摘 要： | 为了解决新疆及甘肃河西等地区山溪性河流急速渠道的水流钎接及消能问题，结合工程实际研究出一种经济合理的消能形式－－陡坡加糙消能形式。对混凝土半球形突体在4种不同间距、10种不同水深情况下的水力摩阻系数进行了试验研究；由多糙度渠道水流阻力分析得出了设计条件半球形突体梅花桩布置时的最佳跨高比；对加糙消能效果进行了比较。

| Abstract: | In order to solve the problem of flow linkingup and energy dissipation of large gradient canal in the mountainous areas in xinjiang Region and Gansu Province,an economic and reasonable pattern of energy dissipation,a pattern of energy dissipation with steep slope and additional roughness,is put forward in light of actual projects.Hydraulic resistance coefficients of concrete semi global convex bodies with four different spans and ten different water depths are researched experimentally.The optimal spanheight ratio of the semi global convex bodies with plum blossom liked layout is obtained by means of analyzing hydraulic resistance of multi roughness of offtakes. Comparisons of energy dissipation effects between different additional roughnesses are made. |
