It is important to understand pullout behavior of geosynthetics in order to design various structures, such as retaining structures reinforced with geosynthetics and anchor systems for covers and liners. This research focuses on anchor systems for geosynthetics that are deployed as part of landfill cover and bottom liner systems.
Specific objective of this research is to make quantitative evaluations of geosynthetic anchor capacity for different configurations of anchor systems commonly used in landfills.
This research consists of the following components:
Experimental - anchor capacity is evaluated from experiments using a geosynthetic pullout shear device
Numerical - finite element modeling of geosynthetic anchor system is conducted
Analytical - currently-available analytical models are reviewed and modified
Some results of this research are published in the following paper:
