What is the maximum load bearing soil capacity of a sandy soil classification?

The maximum load-bearing capacity of sandy soil typically falls around 2000 pounds per square foot (PSF) under ideal conditions. This number is based on the general engineering principles related to soil classifications, where sandy soil is known for its good drainage and relatively low cohesiveness compared to clay or silty soils.

Under typical scenarios, sandy soils can support structures effectively, but their load-bearing capacity can be influenced by various factors such as moisture content, compaction level, and the presence of organic materials. This range of 2000 PSF serves as a baseline for sandy soils that have undergone standard testing and provide a robust foundation for most construction applications.

In contrast, other classifications of soils, such as clay or cohesive soils, tend to have different capacities due to factors like cohesion and the structure of their particles, which results in lower load-bearing capacities relative to sandy soils. Therefore, while multiple options suggest higher capacities, 2000 PSF represents a more widely accepted standard for sandy soil, particularly in construction and engineering contexts.
