The Investigation of the Landfill Settlement Prediction Method

As the method to predict the landfill settlement,Sowers theoretical model has been widely applied at home and abroad and also recommended by the industry Standard for ifs simple formula and less parameters. However, the industry standard formula has some limitations and uncertainties when applied to the specific project. Because it's difficult to determine the model parameter by the standard for we can only get the range value or has to test to get the specific value. Different parameter selection form the scope of the reference parameter could lead to the different prediction results. There are differences in solid waste deposits in different regions, and the test data is not easy to measure for solid waste body sample has the large discreteness. As a result,based on a series of field monitoring data at one of the Beijing waste sanitary landfill site, this article full analyses of the landfill settlement rule in the region, applied the measured data to Sowers model to determine the relevant parameters. Combining theoretical model with the field measured data, this article laid the foundation for analysis the follow-up landfill settlement,and has a reference significance for similar projects.
