This paper presents the measured behavior of an anchored segmental retaining wall. In an attempt to understand the overall mechanical behavior of the anchored segmental retaining wall and to confirm the applicability of the design assumptions, an extensive monitoring program was implemented for a 7-m-high anchored segmental retaining wall. The measured horizontal earth pressures and the inferred tensile loads in the reinforcements indicated that the state of stress within the reinforced soil mass is higher than the Rankine active state of stress and that by Coulomb wedge analysis, approaching to that based on the FHWA design approach for inextensible reinforcements. The measured performance satisfied the minimum performance requirements for the internal stability with a maximum wall movement comparable to that reported for walls with inextensible reinforcements. The wall survived severe rainfalls during and after the wall construction, exhibiting an excellent performance in terms of drainage. Implications and findings from this study are discussed.
