英文摘要	Based on the seepage mechanics of fractured medium and the theory of solute transport, the equivalent continuum model of landfill leachate water and the kinetic model of contaminant transporting in saturated and unsaturated rock and soil medium were established. The models were applied to the preliminary evaluation of a designed valley-type landfill site, and the comparative analysis between three working conditions shows that the vertical stonewall can't be used as a nature seepage control system; the abruption of the HDPE membrane may cause the contamination of underground water behind the landfill; the clay-solidified grouting layer with a thickness of 1 m can prevent the seepage effectively. So the measure with grouting 1-meter thick clay-solidified Slurry and the paving HDPE membrane was suggested. It not only can prevent the contamination of landfill leachate to underground water but also can solve the stability problem of vertical stonewall.
