摘要
对淮南市部的二个垃圾堆集场的研究结果表明，经过８到１０年的垃圾污染作用，堆集场地基粘土的矿物成分和化学成分均发生了改变。变化程度与深度相关。例如：地其粘工中原来蒙脱石含量很高，但由于人渗水的作用使蒙脱石伊利石化以至其含量明显下降。此类水化学反应和矿物变化进一步引起了地基粘土的水理性质改变。
In the basal clay of two waste deposits in the suburbs of Huainan mineralogical and chemical changes depending on depth took place in the upper half of the clay during 8 to 10 years of operation: caused by leachate percolation the formerly high montmorillonit content has decreased by illitisation. These hydrochemical and mineralogical reactions aroused significant changing of the hydro-physical properties of the basal clay.
