【摘要】:土壤盐渍化是目前众多交叉学科研究的一个热点问题,涉及到土壤学、环境科学、岩土工程等学科知识.科学认识土壤中水盐迁移模式及运移机理,对农业工程治理土壤盐渍化以及路基工程预防路基盐渍化具有重要意义.介绍了国内外农业工程领域比较认同的水分迁移模式(毛细管作用假说、薄膜水迁移理论、结晶力理论与吸附—薄膜理论)、盐渍土离子迁移方式(渗流迁移、扩散迁移与渗流—扩散混合迁移)与土壤中水-热、水-盐、水-热-盐运移机理与模型,以及公路工程领域相关的研究进展,并对相关模型原理、异同点、优缺点、适用性及应用状况进行了分析评价.
[Abstract]:Soil salinization is a hot issue in many cross-disciplinary studies, involving soil science, environmental science, geotechnical engineering and so on. It is of great significance for agricultural engineering to control soil salinization and subgrade engineering to prevent subgrade salinization. The water migration modes (capillary action hypothesis, film water migration theory, crystallization force theory and adsorption-film theory) and ion migration mode (percolation migration in saline soil) are introduced in the field of agricultural engineering both at home and abroad, including capillary action hypothesis, film water migration theory, crystallization force theory and adsorption-film theory. The mechanism and model of water-heat, water-salt, water-thermo-salt transport in soil and highway engineering field, and the principles, similarities and differences of models, advantages and disadvantages of the models are also discussed. The applicability and application status are analyzed and evaluated.
