摘要
非饱和水力传导度是多孔介质中水流运动的重要参数之一,在进行较大区域尺度土壤水动力学模型模拟时,选择客观准确而实用的试验方法对其进行测量显得尤为重要。对国内外非饱和水力传导度的试验方法进行了充分的调研,比较了各种主流试验方法的原理和实用范围,并分析了各自的优缺点,突出阐述了适用于野外试验的方法。为进行较大区域尺度土壤水动力学模型模拟奠定了基础。
Unsaturated soil hydraulic conductivity is one of the important parameters of water flowing movement in multi-holes medium, to select a correct and practical experiment method appears particularly important for survey as simulating the soil hydraulic model in big area. Overseas and home experiment methods of unsaturated soil hydraulic conductivity were studied fully in this paper,through comparing the theory and suitable scope of each major experiment methods and analyze their own advantage and shortage,the method suitable for field experiment was described in details to lay a foundation for soil hydraulic model in the big area.
