  Abstract

The relationship between the manufacturing parameters and the compressive behaviors of a traditional bi-planar geonet, the effect of various test conditions on the compression test results for bi- and tri-planar geonets, and the correlation between the normal pressure and the transmissivity of bi- and tri-planar geonets were investigated. The geonet strand inclination can mainly affect the after-compressive strength, i.e., roll-over behavior. For both bi- and tri-planar geonets, the compressive strength decreased and the strain at the yield point increased gradually with temperature . A significant reduction in flow capacity was observed for the traditional bi-planar geonet, and this value was consistent with the compressive strength. These decreases were anticipated owing to the abrupt thickness decrease in the geonet caused by roll-over. On the other hand, no significant decrease was observed in the transmissivity for the tri-planar geonet, which did not roll over.
