渠道渗漏量计算和实测方法金永堂邓湘汉(水利水电科学研究院)本文对各种类型的渠道(如长期输水、周期性工作、临时渠道、非均质水平土层渠道、各向异性土壤渠道以及具有防渗渠道等)的渗漏量计算方法进行了汇兑和分析,指出其优点和应用条件。此外,并对现有的各种实测渠道渗漏方法(如断面流量测渗法、静水测渗法、沉箱测渗法、同心环测渗法以及护面下收集渗漏法等)进行了分析比较和误差计算,同时对计算和实测渠道渗漏量也有一定的参考意义。
Calculation and Measurement Method of Canal Leakage Jin Yongtang Deng Xianghan (Water Resources and Hydropower Research Institute) In this paper, various types of channels (such as long-term water conveyance, periodic work, temporary channels, heterogeneous horizontal soil channels, anisotropic soil channels As well as with seepage channels, etc.) of the leakage calculation method for the exchange and analysis, pointed out its advantages and application conditions. In addition, the existing methods of leakage of measured channels (such as cross-sectional flow infiltration, hydrostatic infiltration, caisson infiltration, concentric annular infiltration and confinement leakage collection) were analyzed Comparison and error calculation, while calculating and measuring the amount of leakage channel also has some reference value.
