“…The results again show a good agreement with those published, and correctly bound almost all of them. Third, in Table 3, a further comparison is provided for the bearing capacity factor , allowing for the presence of a void at different depths beneath the strip footing central line, see [10,12,19]. It has been assumed that the opening width is equal to the surface footing width, and is located within an utterly cohesive soil at an undrained state with cohesion varying in the range 60 300 kPa.…”

“…Xiao, Zhao, and Zhao [18] applied the same method to assess the undrained bearing capacity above voids in two-layered clays. Zhou et al [19] instead used the discontinuity layout optimization approach to determine the bearing capacity above square voids in cohesive-frictional soils, reporting typical failure patterns. Lee and Kim [20] investigated the bearing capacity above multiple square voids in sandy soils and purely cohesive clays, and they also explored the effect of load inclination.…”

“…Their results indicate that the mode of failure depends on the size and location of the voids. Authors in [10] applied the procedure DLO to analyze the stability of footing situated on cohesive-frictional soil with single and dual square voids. The results implied that the presence of voids has a greater impact on c-φ soil compared to that on non-drained soil.…”

“…The underground voids typically occur as a result of the dissolution of soluble rocks, the dynamic loading caused by construction and mining activities, the existence of nearby leaking pipelines, and the subsidence of poorly compacted trench backfill [2]. There are studies on the stability of footings located above voids [3][4][5][6][7][8][9][10] and footings on geosynthetic-reinforced soil with voids [11][12][13][14][15][16][17]. In the literature, researchers investigated the effect of the shape, size, location, and number of voids, as well as the type, dimension, number, and configuration of the geosynthetics.…”

“…Furthermore, the limit analysis theory was employed to study the bearing capacity of strip footings above voids in two-layered clays and rock mass by Xiao et al [39,40]. Zhou et al [10] extended the limit analysis to evaluate the collapse load of the footing-above-void system by using the discontinuity layout optimization (DLO) technique. However, no thorough analysis of the drained bearing capacity of strip footings on sand has been performed and the corresponding N γ values are not available in literature.…”
