Settlement Analysis of Municipal Solid Waste Landfill
In conventional soil mechanics method, the soil particle is known as rigid and its size remains unchanged during a compression. With regard to waste landfill, however, the degradation can decrease the volume of solid particle, produce new gases and liquids. Settlement character, excessive settlement and differential settlement of waste landfill might lead to all kinds of pipelines rupture, and then percolate cannot be expelled and result in rising ground water level. This will threaten seriously the stability of the landfill. It is fundamental to the landfill recycle to calculate the stability of settlement after closure of landfill. Based on the landfill site engineering in Langfang of North China, this article explores a new computing method of the landfill settlement with layering filling and organic matter degradation. Different factors influences on settlement are analyzed by the computer numerical simulation to offer evidence to the landfill recycle.
