Soil bearing pressure
Web5. If P/A exceeds M/S, then the maximum bearing pressure equals P/A + M/S and the minimum bearing pressure equals P/A-M/S. 6. If P/A is less than M/S, then the soil bearing pressure is as shown in Fig. 5-1. Such a soil bearing pressure distribution would normally be considered undesirable because it makes the footing structurally ineffective. WebEdge beams connected to the slab — natural soil with an allowable bearing pressure of not less than 50 kPa or controlled fill compacted in accordance with 3.2.2.2(a)(iii) and extending past the perimeter of the building 1 m with a slope ratio not steeper than 2 horizontal to 1 vertical (see Figure 3.2.2.1).

In a nutshell, bearing capacity is the capacity of soil to support the loads that are applied to the ground above. It depends primarily on the type of soil, its shear strengthand its density. It also depends on the depth of embedment of the load – the deeper it is founded, the greater the bearing capacity. Where there … See more Ground bearing pressure (bearing capacity of soil) is important because whenever a load is placed on the ground, such as from a building foundation, … See more The types of bearing capacity of soil are: 1. Ultimate bearing capacity (qᵤ):the maximum vertical pressure that can be applied to the ground surface, at which point a shear failure mechanism develops in the supporting soil. … See more The most commonly used types of bearing capacity of soil are ‘ultimate bearing capacity’ and ‘allowable bearing capacity’. Let’s take a look at the definitions of these terms first. See more Now that you understand the difference between ultimate and allowable bearing capacity, let’s move on to how we can determine the bearing capacity (bearing pressure) of soil for use in the design process.
