The Study On Controllability Settlement Of The Mixture Of Municipal Solid Waste And Construction Waste Landfill

Municipal solid waste landfill with China's economic development and urban construction have been expanding around the city accounted for a large number of land. And decreasing land resources, urban development from the center to spread around, so a lot of new building construction needs in the neighboring city of miscellaneous landfill field (By the solid waste landfill and construction is formed) . However, miscellaneous landfill can not meet the requirements of building the foundation bearing capacity, and also own a certain amount of the settlement, often can not be directly used as a building foundation. So for miscellaneous landfill settlement of the research is essential.In view of the miscellaneous fill the landfill settlement ,not only with the special nature of the miscellaneous fill,and also filling landfill miscellaneous local hydro-geological, environmental, and other climate-related uncertainties. This article discusses the methods of mathematical randomness of BP neural network forecasting landfill settlement viability of a combined landfill Beijingnanzhan the use of secondary works on the prediction model was verified, the forecast for a draw Miscellaneous filling landfill settlement of the BP neural network model. And the establishment of the random use of mathematical models of Beijingnanzhan settlement of the landfill had forecast.As the filling miscellaneous landfill is not suitable for direct use as abuilding foundation, so its characteristics of the selected Zhatu pile, dynamic,dynamic Zhatu grouting, thin-walled tube cast-in-place concrete pile foundationtreatment And random use of mathematical methods of principal componentanalysis of these four types of ground treatment programs optimized choice.Miscellaneous for filling landfills as the construction of the second land-usetechnology to deal with the foundation has done a quantitative comparison study.
