Development of Tabriz metropolis on marl layers and increased \ tendency to build high-rise \ buildings have \ resulted in deep \ excavations in these layers. Restrictions of work space have resulted in using soil reinforcement methods in excavations, including grouted anchors. Tabriz Marl is a lacustrine carbonate sedimentary outcrop that surrounds eastern, northern, and southern regions of city in the East Azerbaijan Province of Iran and classified as clayey or silty soil with high plasticity. The objectives of this study were to evaluate the load carrying capacity of tension type grouted anchors implemented in Tabriz marl, their behavior against creep tests and long-term monitoring against lock-off tensile loads. To this purpose, ten full-scale similar anchors were constructed with free length of 4 meters, injected (bonded) length of 3 meters and diameter of 11 cm in marl soil in experimentation site with an area of 800
