摘要
中国广泛使用考斯加可夫经验公式来估算渠道输水渗漏损失 ,在渠道实际运行中 ,存在一些缺陷。为此 ,根据Davis -Wilson公式 ,并考虑使用的习惯性和方便性 ,建立了渠段输配水损失与渠道断面尺寸、水力条件、土壤类型、地下水埋深等因素相关的经验公式 ,同时将渠道衬砌等其他所有因素一并考虑在渗漏折减系数中 。
The empirical formula of Kostiakov is widely used in the canal seepage loss estimation in China, which has defect in real operation of canal. Therefore, the empirical formula is established according to Davis-Wilson equation, with consideration of practice and convenience. The formula takes into consideration of the relationships between water-transportation-and-allocation seepage loss and the sizes of cross-section of canal, hydraulic condition, soil type, groundwater depth and other factors. The effect of canal lining is also considered in the coefficient of seepage diminishment, and suggestion for estimation of the coefficient by real measuring is put forward.
