| 摘 要： | 基于有压双套环入渗仪进行了渠床入渗试验,分析了渠道水深与渠床土壤入渗能力间的关系并讨论了其作用机理。结果表明:同一土壤质地条件下,渠床土壤入渗能力随渠道水深的增加而增大,90 min累积入渗量和相对稳渗率与水深之间均呈指数关系;随着渠道水深增加,地表入渗界面处压力势增大,是地表处水分运动通量增大,渠道渗漏量增加的根本原因。研究结果可为渠道渗漏损失的计算提供依据。

| Abstract: | Based on the double-ring water infiltration experiments in canal soil with different water head,the effects of influence of water head on infiltration,and the change of infiltration capacity of canal soil was analyzed.The experiment results showed that the infiltration capacity and infiltration rate of canal soil increased with the water head increased,the relationship conformed to the index function law,and pressure potential is the main factor affecting infiltration capacity.The study result provides a basis for the calculation of canal seepage. |
