    Calculation of Bearing Capacity. For the calculation of bearing capacity of soil, there are so many theories. But all the theories are superseded by Terzaghi’s bearing capacity theory. 1. Terzaghi’s bearing capacity theory. Terzaghi’s bearing capacity theory is useful to determine the bearing capacity of soils under a strip footing.

    Bearing Capacity Of Different Types Of Soil

    Bearing capacity is the capacity of soil to support the loads applied to the ground. The bearing capacity of the soil is the maximum average contact pressure between the foundation and the soil which should not produce shear failure in the soil. Ultimate bearing capacity is the theoretical maximum pressure which can be supported without failure.

    A CLSM compressive strength of 50 to 100 psi is equivalent to the bearing capacity of a well-compacted soil. Maintaining CLSM strengths at low levels is critical in those projects where future excavation will be required, and therefore it is often critical that mixtures be proportioned in a manner so as to minimize later-age strength increases.
