The correct answer is D. Bearing capacity of a soil is independent of rate of loading.
Bearing capacity is the maximum load that a soil can support without failing. It is a function of the following factors:
- The type of soil: The bearing capacity of a soil is affected by its type, such as sand, clay, or silt.
- The shape and size of the footing: The bearing capacity of a soil is affected by the shape and size of the footing, which is the area of the structure that is in contact with the soil.
- The amount and direction of load: The bearing capacity of a soil is affected by the amount and direction of the load that is applied to it.
- The rate of loading: The bearing capacity of a soil is not affected by the rate of loading.
The bearing capacity of a soil can be determined by conducting a bearing capacity test. This test involves applying a load to a soil sample and measuring the settlement that occurs. The bearing capacity of the soil is then calculated based on the results of the test.
The bearing capacity of a soil is an important factor in the design of foundations. The foundation of a structure must be designed to support the load of the structure without exceeding the bearing capacity of the soil. If the bearing capacity of the soil is exceeded, the foundation may settle or fail.
