摘要
The process stress of sanitary landfill is changing constantly in use,which will cause the penetrative conditions to change in landfill liner.It is of great realistic significance to explore the influence of these changes on the seepage performance of landfill liner.The permeability of modified loess soil by bentonite was tested with a flexible-wall permeameter,and the impact on coefficient of permeability of the modified loess soil was investigated under different conditions of penetration time,confining pressure and osmotic pressure.The research results show that coefficient of permeability of modified loess soil fluctuates in the same order in the initial stage,and the coefficient of permeability tends to be stable.Furthermore,the coefficient of permeability of modified loess soil can be reduced in the same order with the increasing confining pressure and osmotic pressure.
