This article is a review of the role PREDICT second landfills throughout KS * Watts, JA Charles and HD Skinner * * Building Research Establishment Ltd, Watford, at the Conference of waste in September 2006 in Stratford-upon-Avon, UK.Watts and Charles (1990, 1999), the mechanism of the system were described in detail. These can be classified as follows: - the immediate compression partially saturated waste - An application of immediate load in compression is a partially saturated landfill product.
This condition is evident in the initial operation of filling and adding more waste in the existing tank. - Compression Creep partially saturated waste - an approximate linear relationship exists between the compression caused by physical processes of flow and creep of the logarithm of time, to be paid from the time of loading or after the grant was approved. - Fill the consolidation of saturated primary waste - The application of the load of saturated fat (below the level of leachate) may generate positive neutral pressures.
were, leachate, removed after the pore pressure, the, leachate, long-term solution is to scan continue to fill similar effects due to physical compression in a partially saturated. - Bioconsolidation - a strong long-term reduction of the fill volume is probably due to biological degradation of waste. The agreement, which is based on biodegradability will be much larger than the physical processes and can be completed by affected by changes in biochemistry, leachate, . Therefore, all long-term solution of waste is probably due to the cumulative effect of physical and biological degradation and compression, but the latter method, the dominant cause of long-term, leachate,, leachate, solution is full of waste with high organic content.
The extent and speed waste treatment depends on the complex interaction between physical and biological degradation processes and depending on the initial composition, density and moisture content of waste, the leachate level and time since placement. The study describes and illustrates the measures in places where it refers to relatively high levels of leachate. While the behavior of each dump is probably related, leachate, to the general model, the magnitude of the movements below, may differ materially and depend on data specific to other situations.
expect a higher proportion of unsaturated residues of mechanical components and biological results in larger settlements. The field data is relatively easy to acquire and can both generic and specific patterns in their behavior. One of the main advantages of this method is that the control field can be started and after completion of the landfill installed after the general model. It should be noted that the accounting data obtained from the time of completion and the information (the data) for admission, completion, leachate, and reduction of waste at any point in a landfill is essential for the process to accurately predict future movements.
