Abstract

The heap of new waste in landfills impose a large additional load on leachate pipelines constructed under existing landfill sites. There is urgent need to address safety problems caused by the new effect that is produced on these pipelines. Based on a modified Spangler model, the deformations of HDPE pipelines of different diameters and different wall thicknesses under garbage load were calculated and compared with design requirements. The calculation results show that the upper load has remarkable effect on the deformation of pipeline ring cross sections, the deflection of pipelines and loop tension stress of pipe walls. This was due to the differences of diameter and wall thickness of different HDPE pipelines which responded differently to the upper load.
