Soil bearing capacity is the maximum amount of weight (pressure) that soil can support before it fails.expand_more It's an important concept in civil engineering, especially when it comes to designing foundations for structures.expand_more
There are two main types of bearing capacity:
Ultimate bearing capacity: This is the maximum pressure that the soil can withstand before it collapses completely.expand_more It's a theoretical value that is not used in real-world engineering design.expand_more
Allowable bearing capacity: This is the safe working load that the soil can support without failure or excessive settlement.expand_more It's calculated by dividing the ultimate bearing capacity by a factor of safety (usually between 2 and 5).expand_more The factor of safety accounts for uncertainties in the soil properties, construction methods, and the loads that will be placed on the foundation.expand_more
The bearing capacity of soil is influenced by a number of factors, including:
Soil type: Sand and gravel generally have higher bearing capacities than clay and silt.expand_more
Soil density: Denser soils can support more weight than looser soils.expand_more
Moisture content: Wet soil has a lower bearing capacity than dry soil.expand_more
Depth of foundation: The deeper the foundation, the greater the bearing capacity (up to a certain point).expand_more
Presence of groundwater: Groundwater can reduce the bearing capacity of soil.expand_more
Determining the bearing capacity of soil is a complex process that typically involves soil testing and engineering analysis.expand_more A geotechnical engineer can assess the specific site conditions and recommend an appropriate allowable bearing capacity for the foundation design.
