Maximum soil bearing capacity of different types of soil

The load of structure is coming on the soil. So we need to know the bearing capacity of the soil. Bearing capacity of soil is used to indicate the maximum load per unit area which is determined by a) Method of loading or b) Method of dropping weight. Dividing the ultimate soil bearing capacity by a safety factor we get the maximum safe bearing capacity of soil which is used to design foundations.

Below are the maximum soil bearing capacity of different types of soil:

Type of soil                                                             Maximum safe bearing capacity kg/m2

1. Soft, wet clay or muddy clay — 5,000

2. Soft clay  — 10,000

3. Fine, loose and dry sand  — 10,000

4. Black cotton soil  — 15,000

5. Moist clay and sand clay Mixture — 15,000

6. Loose gravel — 25,000

7. Medium clay — 25,000

8. Medium, compact and dry sand — 25,000

9. Compact clay — 45,000

10. Compact sand — 45,000

11. Compact gravel — 45,000

12. Soft rocks — 45,000

13. Laminated rock such as sand stone &
      Lime stone — 165,000

14. Hard rocks such as granite, diorite, trap–  330,000

    what is the design bearing capacity if the measured bearing capacity of a made-up soil is, say, 300kn/m2?
