| 摘 要： | 野外渗水实验和机制研究的结果表明:在暂时性饱和水入渗条件下,浅部黄土中可以形成裂隙中的水分向孔隙的“单向流”过程;在非饱和流状态下,黄土中的裂隙和大孔隙不起导水作用,而产生水流屏障效应。

| Abstract: | Results of the field infiltration test and analysis of mechanisms governing water flow indicate that: under temporal saturated infiltrating condition "one - way flow "(from fracture to matrix) can occur in shallow loess; under unsaturated condition fracture and big pore in porous matrix do not play a role in water conducting, but result barriering effect. |
