Stability Analysis Of ShuangMa Dump In XiangTan City

With the rapid growth of urban population and the rapid development of industrialization,the problem of urban solid waste disposal is also increasing.At present,the landfill has gradually become a safe,economical and effective waste disposal method.And its stability has an important influence on the economic and security of landfills.Therefore,it is of great significance to study the stability of the slope in the landfill.Based on reading lots of documents,this paper introduces the structure,type,instability modes,causes,and the main influence factors and stability analysis of landfill;combined with slope stability analysis method,and use FLAC3 D software for special landfill bottom liner along the sliding system,on the basement of testing,the calculation stability analysis of the landfill and the local stability analysis,prediction of landfill Xiangtan Shuangma landfill and closed after the slope stability.Then the Lizheng geotechnical,establish different working models,the model also considers the effect of sliding along the bottom of the liner system,respectively along the geotextiles-geomembrane,geomembrane-GCL;the stability of landfill storm conditions is considered at the same time,and the landfill design and construction are given instructronal advice.
