( Welcome to the Seventh article. For more, please visit the links at bottom of the page. )

The capacity of soil to bear the loads coming from the foundation and transfer it safely is called Bearing Capacity of Soil.

Generally, Bearing capacity of soil is not brought in consideration for small structures like residential houses. But it is highly important for the big structures like skyscrapers, bridges, massive concrete structures, towers etc.

For the normal consideration, IS: 1904-1961  has given the following values for different types of soils: 
( Any necessary calculation can be done by taking the values given in the table by visual inspection of the soil type)


How to determine bearing capacity of soil in site ?

There are different methods for determining the bearing capacity of the soil but the method mostly practised is Plate Load Test.

Plate load test is one of the complex method and it consumes a lot of time, resources and manpower for the complete test procedure.
It cannot be easily understood by reading the procedures. So, I have attached a practical example of plate load test with the procedure, data and analysis. Hope it will help a lot.
