| Presently, sanitary landfill is the predominant method of municipal solid waste (MSW) treatment, so does it in the long time of future. Landfill leachate is principal contamination produced from sanitary landfill. It has the latent threat to the environment and the human health. The control and the governing landfill lecheat need a research on its production and moving rule. Therefore, to calculate the Hydraulic conductivity of landfill is extremely vital significant about the control and the government research of landfill leachate, as well as the hydraulics correlation analysis, the design and the management of landfill. On the basis of reading a large number of references extensively, the author analysis various kinds of factor that influence landfill hydraulic conductivity, and research landfill hydraulic conductivity carefully. At last, the author draws the following conclusion.(1) The main factors that effect Hydraulic conductivity of landfill are ingredient of landfill and landfill settlement.(2)The hydraulic conductivity of Unit landfill is the exponential distribution in the vertical direction of landfill.(3) Through setting up mathematical model of Hydraulic conductivity of Unit landfill and using SPSS to solving the parameter of the model, there is a conclusion that value of Hydraulic conductivity within a certain limit.(4) Using the model, the computed result of the Hydraulic conductivity of Unit landfill of Chengdu Chang-an Landfill site indicated the hydraulic conductivity of Unit landfill of Chengdu Chang-an Landfill site in 3.57× 10-5m/s4.88× 10-8m/s scope.
