含氟强酸性介质下土层的渗透性及其分析——以湖北大峪口工程黑冲磷石膏渣场为例

THE PERMEABILITY AND ANALYSIS OF THE SOIL LAYER CONTAINING FLUORINE WITH STRONG ACIDIC MEDIA——WITH HEICHONG PHOSPHO-GYPSUM SLAG SITE OF HUBEI DAYUKOU PROJECT AS AN EXAMPLE

酸性介质下土层的渗透性是环境工程地质研究的新课题.本文以湖北省大峪口工程黑冲磷石膏渣场为例,研究了在含氟强酸性介质下土层的渗透性能,得出了土层在含氟强酸性介质下其渗透性主要取决于土层表面形成的板结层,其渗透系数较在水介质作用下更小的结论.

The permeability of soil layer under the condition of acidic media is a new research subject of environmental engineering geology. In this paper, taking the Heichong phospho -gypsum slag site of Dayukou mine/fertilizer project as an example , by studying the permeability of soil layer containing fluorine with strong acidic media. conclusions have been drawn that its permeability mainly depends upon the harden layer formed at soil surface, and its per-meabilty coefficient being smaller under the action of water.
