Methods of Determining Bearing Capacity

Based on the theoretical approaches, bearing capacity of a soil can be found knowing the strength parameters, density, depth of foundation and water table possible. Terzaghi’s bearing capacity theory has been used mostly which suits most of the field conditions.

Field plate-load test can be conducted at the stipulated depth of foundation. Indirect methods such as penetration tests may be used.

Bureau of Indian Standards has given presumptive bearing capacity values, which is presented in Table 15.1.
