摘　　要：将室内试验确定的适宜加沙量用于城市卫生填埋场的粘土衬垫系统中,用平面有限元方法计算填埋场粘土衬垫的总应力,分析不同地基条件下粘土衬垫厚度对衬垫应力分布的影响。Adding appropriate volume of sand determined by indoor test to the clay packing system of municipal sanitary landfill,the total stress of clay packing of the landfill is calculated by flat finite element method.Effects of thickness of clay packing on stress distribution in the clay packing are analized for different conditions of foundation to provide theoretical reference value for economically reliable operation of the landfill and maximizing its space.
