摘　　要：灌溉渠道渗漏损失的确定对于正确计算灌溉水利用系数具有重要的作用。目前,其主要计算方法有现场试验方法、经验公式法、比拟法、数值方法等。而渠系建筑物未修建以前,准确地计算渗漏量,对于其建筑工程的防渗体系结构、投资及后期运行等有着重要的意义。文章对目前几种方法进行比较分析,并通过工程实例,分析上述方法计算渗流量的实用性。The determination of the leakage loss of the irrigation channel plays an important role in the correct calculation of the irrigation water utilization coefficient.At present,the main calculation methods include field test method,empirical formula method,analogy method,numerical method,etc.Before the construction of the canal system,accurate calculat on of the leakage amount is of great significance to the anti-seepage system structure,investment and later operation of the construction project.Therefore,several current methods are compared and analyzed,and the practicality of the above methods for calculating seepage flow is analyzed through engineering examples.
