Effect of Relief Shelves on Cantilever Retaining Walls

Retaining walls are a part of everyday infrastructure, from retaining soil in mountain slopes to harbor structures. With the expectation to retain higher backfills, new and improved design methodologies, such as reinforced retaining wall, lightweight backfilling, are being implemented. A new method of construction consisting of relief shelves attached to the backfill side of the stem provides relief to the lateral pressure acting on the wall, thus reducing the overturning moment of the wall during stability analysis. Available literature suggests the use of retaining wall with shelf/shelves with experimental and theoretical computations based on provision of one or two shelves. The effect of using more than two shelves has not been studied extensively. This paper studies the effect of multiple shelves have on the lateral earth pressure acting on the stem. A parametric study was carried out to understand the variation of lateral earth pressure with the change in length and number of shelves at the back of the retaining wall. It is observed that the increase in number of shelves corresponds to reduction in total thrust and moment of the lateral earth pressure in comparison with that of single shelved retaining walls. It is also observed that short multi-shelved walls are much more efficient compared to long single shelved retaining walls of the same shelf length.
