Thank you 6.3 Refer to Figure 6.7 and consider a rectangular foundation. Given:B = 1.5 m, L= 2.5 m, Dy= 1.2 m, H = 0.9 m, d' = 40°, d = 0, andy = 17 kN/m³, Using a factor of safety of 3, determine the grossallowable load the foundation can carry. Use Eq.

The variations of Nº, Nº, and N with H/B and the soilfriction angle ø' are given in Figures 6.8, 6.9, and 6.10, respectively.It can be seen from Figures 6.8, 6.9 and 6.10 that when the depth to the rigidbase H decreases, the bearing capacity factors and hence the ultimate bearingcapacity of the foundation increase. It can also be seen that when H>B,especially for lower friction angles, one can conservatively ignore the presenceof the rigid base and use the general bearing capacity factors Ne, Ng, and Ny(Table 5.3).
