Study of Soil-Water and Pore Size Distribution Properties of the Humus
The humus of domestic waste was of great practical significance to the sustainable development of landfill.The effects of landfill age,initial dry density and the maximum particle size on soil-water and microscopic properties of humus were studied by centrifuge test and nuclear magnetic resonance.The unsaturated hydraulic parameters of humus were obtained by combining experimental data with VG model.The initial dry density mainly affects the saturated water content and air intake value of the compacted sample,and the soil-water characteristic curves with different dry densities tended to coincide within the range of more than 100 kPa.With the increase of landfill age and initial dry density,the pore diameter decreased.With the increase of the maximum particle size,the pore size distribution showed the opposite trend.
