Resumen:
This paper is about the long-term performance of a geomembrane installed as a liner at the base of a municipal solid waste landfill. This landfill was built on very soft and highly compressible lacustrine clay which is also being subjected to the effect of regional subsidence caused by water-pumping from an underlying aquifer. The paper describes the setting up and the results of a large scale field load test that was performed in the waste fill. Based on the behavior observed during the load test, a 3D finite element model was established to replicate the consolidation process in the underlying soil in order to describe the long-term performance and future stability of the totality of the solid waste landfill, taking into account the geomembrane properties and changes in the waste fill's height. The study disclosed the consequences of having the geomembrane, on the general stability of the landfill.
