“…The results also showed that the beneficial effects of reinforcement at a low settlement ratio (s/B) can be achieved maximally when the top layer spacing is less than 0.25B. Alternatively, Arab et al [27] conducted a numerical analysis on the strip footing supported by sandy soil by using a…”

“…Alternatively, Arab et al . [ 27 ] conducted a numerical analysis on the strip footing supported by sandy soil by using a hardening soil model. They reported that for the geometrical parameters u / B = h / B = 0.5, and b / B = 4, the effect of the increasing number of geogrid layers ( N ) on the bearing capacity of the geogrid reinforced soils increased the bearing capacity and slightly increased the overall stiffness of the reinforced sand.…”

“…In regards to the soil behaviour with sandy soil classification, numerous analytical studies have contributed to the knowledge of soil-structure interaction conducted by several researchers towards the bearing capacity of geogrid-reinforced soil foundations [13][14][15][16][17]. Additionally, innumerable numerical models which time and cost-saving have been carried out to investigate the bearing capacity and the settlement of reinforced soil [9,[18][19][20][21][22][23][24][25][26][27][28][29]. The concept of reinforced soil as construction material which is based on the existence of soil-reinforcement interactions due to tensile strength, frictional, and adhesion properties of the reinforcement was first introduced by the French architect and engineer Henri Vidal in the 1960s [29].…”

The main cause of problematic soil failure under a certain load is due to low bearing capacity and excessive settlement. With a growing interest in employing shallow foundation to support heavy structures, it is important to study the soil improvement techniques. The technique of using geosynthetic reinforcement is commonly applied over the last few decades. This paper aims to determine the effect of using geogrid Tensar BX1500 on the bearing capacity and settlement of strip footing for different types of soils, namely Al-Hamedat, Ba’shiqah, and Al-Rashidia in Mosul, Iraq. The analysis of reinforced and unreinforced soil foundations was conducted numerically and analytically. A series of conditions were tested by varying the number (N) and the width (b) of the geogrid layers. The results showed that the geogrid could improve the footing’s bearing capacity and reduce settlement. The soil of the Al-Rashidia site was sandy and indicated better improvement than the other two sites’ soils (clayey soils). The optimum geogrid width (b) was five times the footing width (B), while no optimum geogrid number (N) was obtained. Finally, the numerical results of the ultimate bearing capacity were compared with the analytical results, and the comparison showed good agreement between both the analyses and the optimum range published in the literature. The significant findings reveal that the geogrid reinforcement may induce improvement to the soil foundation, however, not directly subject to the width and number of the geogrid alone. The varying soil properties and footing size also contribute to both BCR and SRR values supported by the improvement factor calculations. Hence, the output complemented the benefit of applying reinforced soil foundations effectively.

“…A soil's bearing capacity is influenced by properties such as shear strength [19]. Dense sand has a higher bearing capacity than loose sand due to its density [20]. A shallow foundation is used when the soil's bearing capacity is sufficient to safely support the structure's load [21].…”

Ethiopia is almost mountainous and hilly in topography, with many rivers flowing from the cities' centers. To facilitate transportation, a bridge across the Berbere Wonze River must be built. The bearing capacity of foundation soil is important for foundation design because it can carry heavy loads from the superstructure. The primary goal of this experimental geotechnical investigation is to determine the bearing capacity of foundation soil for the design of bridge foundation at Berbere Wonze River in Amahara Region South Wollo, Kombolcha, Ethiopia. The foundation investigation work includes a Dynamic Cone Penetration (DCP) test, a Standard Penetration Test (SPT), visual identification, groundwater monitoring, soil sampling, and subsequent laboratory tests on representative samples to determine the physical and engineering properties of the subsurface formations and soil underlying the proposed bridge sites. These are to provide safe and cost-effective foundations based on a combination of field data and laboratory test results.
