Soil bearing pressure

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. The type of … See more WebJul 17, 2013 · An unreinforced soil-cement pad may distribute the footing load at something like 45 degrees, but if the footing is large, the bearing pressure is still high for soil. CBR of 10 - 12 is not high, and may represent only a thin compacted subgrade. The pad may support load until the soil-cement shears, then a punching failure occurs catastrophically.

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.
