| Popis: |
This study deals with the relationship between short-term compression strength and transmissivity properties of geonets and its effect on the result of land filling design. The result shows that the compression behaviors undergo some plateau or roll-over region right after yielding point and this phenomenon will induce some significant decrease in hydraulic properties. Also, the hydraulic properties affected on designing results differently under low and high normal pressure conditions in case of bi-planar geonet. Large differences of qallow values between the expected transmissivity value which comes from linear regression curve and true value especially in high normal pressure condition were observed. From these results it is assumed that when designing with geonet drainage material used in waste landfill, the loading condition must be considered and true transmissivity value which comes from the real hydraulic test should be used than expected values. |
