Research of antiseepage slurry based on clay used in waste landfill sites;

Based on survey results of four waste landfill sites in Beijing which taken at random,some problems in waste landfill sites were noticed including waste overfilling,low ratio of collection and utilization of landfill gas.

Then,the main factors influencing the stability of waste landfill sites were pointed out.

Effect of groundwater table on performance of liners in waste landfill;

Analysis of tensile force of geosynthetics placed on side slope in waste landfill;

It was concluded that construction of a waste landfill would bring negative impacts on the vegetation biomass,plant diversity and landscape in the related area,and mitigating measures as far as afforestation and proper design were needed.

The methane(CH_4) emission from MSW landfill has effect on global warming.

The long-term settlement of MSW landfill resulting from decomposition will usually represent the major proportion of total settlement, and it is likely to continue for many years.
