| 摘 要： | 糙率是渠道水力设计的关键技术参数之一，其值的准确选取决于已建工程原型观测成果的类比。选择3条不同衬砌特性的混凝土渠道进行糙率原型观测，对观测方法及步骤做了较详细描述；计算出了3条渠道的糙率，对其存在误差进行了分析探讨，可为今后进一步开展相关课题研究积累经验并供同行参考。

| Abstract: | Roughness is one of the key technical parameters for hydraulic design of canal and accurate selection of its value depends on the analogy of results obtined from prototype observation of existing projects.3 concrete canals with different lining characteristics are selected for prototype observation on roughness.Methods and measures of observation are described in detail.Roughness factors of 3 canals have been calcualted and their existing errors have been analized and probed into for reference and for accumulating experience in further correlated research. |
