Experimental and Numerical Modeling of Geosynthetic Anchor Trench

Multi-layer liner systems employed in waste containment applications, require an effective and economic anchorage system to secure the installed geosynthetics against applied short-term and long-term loading conditions. Observations of constructed facilities indicate that the anchorage capacity determined during design is often significantly different from actual (field) anchor capacities. This paper will present research currently being performed to evaluate the anchorage capacity through experimental and numerical modeling. Results obtained from the analyses can be integrated to develop modifications to existing analytical models for practical design applications.
