Introduction

Proper estimation of bearing capacity is a key factor in designing geotechnical structures. There is famous equation for estimating the bearing capacity of structures; however, when it comes to thin-walled foundations, to the best of authors’ knowledge, few studies proposed analytical bearing capacity equations for thin-walled foundations. This is generally attributed to the fact that utilization of thin-walled foundation is not common. Thin-walled foundations are used in soils with low strength at the surfacelike costal projects. Therefore, in the recent past years, attempts have been made to predict the bearing capacity of this kind of foundations using relatively new techniques like artificial intelligence [1]. Several authors also showed that when possible thin-walled foundations perform better compared to the conventional footings in terms of bearing capacity. In this regards, Rezaei et al. [1] conducted an experimental study to investigate the effect of walls on the bearing capacity of foundations. Their results suggest when wall length-to-footing width ratio (Lw/W) increases from 0.5 to 1.12, the bearing capacity of the foundation is enhanced 0.5 times. Their footing load tests were conducted in both loose and dense poorly graded sands. Alaghbari and Mohamedzein [2] and Eid et al. [3] mentioned that incorporation thin walls for the spread foundation provide an enclosure in which the soil is confined which consequently leads to an enhancement in the bearing capacity of foundations. According to Alaghbari and Mohamedzein [2] study, when walled foundation is used instead of the conventional foundations, enhancement of bearing capacity in the range of 1.5–3.9 is expected. In another study, Al-Aghbari and Dutta [4] reported that providing thin walls leads to an increase in the bearing capacity from 11 to 70%. Mana et al. [5] stated that the failure mechanism of a footing with two structural skirts is similar to a conventional footing which has an embedded depth equal to skirt lengths. Their conclusion recommends the importance of thin walls in increasing the bearing capacity. Similar conclusions were drawn by Nazir et al. [6, 7]. Eid [8] also stated that providing thin walls can lead to improvement in the bearing capacity by a factor in the range of 1.4–3. Wakil [9] and Wakil [10] also observed remarkable enhancement in the bearing capacity of foundations when structural skirts are used. In a more recent study, Momeni et al. [11] concluded that providing thin walls for spreads foundations can improve their bearing capacities by a factor of 2. Saleh [12] stated that skirted foundations perform better compared to the conventional spread footings. Fattah et al. [13] also stated that the use of skirted foundations is common more especially when the likelihood of scour from water is high.
