| Abstract | ||||
| Sabkha soils can be found all over the world specially, in hot arid areas. This soil is regarded as problematic because of its low bearing capacity and excessive settlement which creates problems to any type of structures. Consequently, the aim of this paper is to predict the behavior of strip footing founded on reinforced Sabkha soil using three different methods utilizing finite element method analysis. First, beneath the footing, a compacted sand layer mixed with randomly dispersed polypropylene fibers (PP) is used. Moreover, a compacted sand layer reinforced with geogrids is used. Finally, investigate the effect of using a sand-rubber mixture layer below as a foundation soil below the footing. The effects of these methods on strip footing bearing capacity and settlement were studied using the finite element method software Plaxis 2D ver. 21. Therefore, it was determined that adopting these procedures boosts the strip footing bearing capacity by a substantial amount, particularly when utilizing the first method which is utilizing the fiber reinforced sand layer over the weak sabkha soil layer. Also noticed was a reduction in soil vertical displacements under foundation for the same values of stress applied to footing. | ||||
