Abstract: The present work evaluates the behavior of 26 reinjectable and prestressed anchors executed during the construction of a ground anchored wall in the city of Congonhas, Minas Gerais, with the purpose of stabilizing a slope near a railway of MRS Logística. It refers to a 4.5-m high retaining wall, 30 m in length, and wall thickness of 0.25 m, with three anchors’ lines, totalizing 36 anchors. The anchors were installed in a soil primarily composed of sandy silt with ore. The anchored length was 6.8 m. During the acceptance tests, significant differences in load capacity were verified, despite the geotechnical characteristics being alike. This work aims to analyze the behavior of anchorages, as well as the resistance gain through the increase of injection numbers, and finally the possible causes of the divergence in the results.
