            Abstract: Technology of mechanically stabilized earth walls (MSE wall) has been used commonly in construction around the world since the 1970s. In our country, this technology is quite new and has only been used in some construction several years ago. In addition, there is little research not only about ultimate load of retaining wall in service, but also about the corrosion of steel reinforcement in the wall over time. Correspondingly, this paper presents some results on ultimate loads, the process of stress – strain – displacement of MSE wall during the construction and in service (the reinforcement is corrosion over time), based on reduced 1/10 scale model and computational model.

Keywords: limited load, depletion, mechanically stabilized earth wall (MSEW), corrosion effect, physical model, computational model, tensile strength, reinforcement.
