【摘要】 以陕西关中地区马兰黄土为对象，通过对试验测定结果的分析，得到非饱和黄土（Ｑ＿３）的含水量与基质吸力相关关系的数学模式，分析表明：该数学模式能较好地表征马兰黄土在较大的基质吸力变化范围内含水量与基质吸力的关系更多还原

【Abstract】 In this paper,the malan loess on Guanzhong area in Shaanxi province has been studiedand a mathematic model of correlation between water content and matrix suction of unsaturatedloess has been obtained through the analyses to the measured results of experiment.Analyses showthat the mathematic model can excellently demonstrate the relation between water content and ma-trix suction of Malan loess in a large varying range of matrix suction.更多还原
