Variation of fluid conductivity with settlement of domestic waste

摘要

Domestic waste (MSW) can be considered as a gradually changing porous medium. This paper reports tests of a new type on a waste sample in order to get correlations between mechanical and hydraulic properties. Compression tests coupled with gas permeability tests have been made on waste sample taken from a hole drilled in a French landfill. The apparatus used for these tests is an oedo-permeameter developed in Lirigm-LTHE. In a second stage, the oedo-permeameter cell has been modified to carry out retention tests on a waste sample under compression. These tests allow to get water retention curve and to assess pores volumetric distribution of the waste.
