垂向入渗条件下土壤的洗滤淡化脱盐问题,是水利土壤改良生产实践中经常碰到的问题。本文着重对渠道排水、垂向渗滤的土壤脱盐为典型,研究了浓度时、空分布的准确表达式,并以此求算洗滤地块中的盐分浓度的分布和变化,其结果对实际有一定参考价值。 Under the condition of vertical infiltration, the problem of soil desalination and desalination is the problem often encountered in the practice of water conservancy soil improvement. This paper focuses on the channel drainage, vertical percolation of soil desalination as a typical study of the concentration, the spatial distribution of the exact expression, and thus calculate the distribution of salt concentration in the landfill block and changes in the results of the actual Have some reference value.
