In general, retaining walls are constructed on various slopes or vertical surfaces of cut-off sites formed by civil works such as roadside slopes, embankments, riverbanks, and landscape walls to support the soil on the back side to prevent its collapse. It is constructed in consideration of factors applied to the retaining wall.

Such a retaining wall cuts the soil in the construction area, constructs a form with reinforcing bars and panels, etc., then pours concrete into the form for curing, and reinforcing soil containing soil, crushed stone or rubble, etc. on the back surface of the reinforced concrete It is usually built by filling the

In the case of such a reinforced concrete retaining wall, the resistance moment generated by its own weight with respect to the soil at the bottom of the retaining wall is greater than the overturning moment that tries to overturn the vertical wall part of the retaining wall so that the retaining wall is not overturned by horizontal earth pressure. By having a support structure, there is an advantage that a separate anchor means for supporting the retaining wall is not required.

However, these reinforced concrete retaining walls are undesirable due to the enormous cost and time required for construction, such as molding, curing, excavation, and filling, and also have aesthetic problems. Retaining walls are widely used.

The retaining wall constructed by the retaining wall blocks is generally constructed by stacking retaining wall blocks in several stages in the transverse direction in a prefabricated manner and then filling the rear surface with reinforcing soil. In order to prevent the point from collapsing due to a moment, various support methods are employed. Among these support methods, the resistance anchor method is mostly constructed.

That is, the resistance body anchor method fixes the front end of a bar, such as a reinforcing bar, steel bar, or FRP bar, to the retaining wall block, and fixes the rear end of the bar to a concrete resistor embedded in the reinforcing soil. It is a method of supporting the retaining wall by the frictional force of the bar.
