What does soil strength measure in relation to soil properties?

The measurement of soil strength is primarily focused on the soil's ability to resist deformation. Soil strength plays a crucial role in engineering and geotechnical contexts, influencing how well the soil can withstand loads or forces applied to it without undergoing any significant deformation or failure. This property is essential for determining the viability of construction projects, as it affects stability and load-bearing capacities.

Soil strength is determined by factors such as cohesion, friction between soil particles, and the overall density of the soil. When assessing the stability of structures like buildings, bridges, or embankments, understanding how the soil performs under stress is critical. High soil strength indicates a better capacity to bear loads without collapsing or shifting, whereas inadequate soil strength may lead to issues such as landslides or structural failures.

While studies regarding soil can encompass aspects like moisture retention, pollutant filtration, and organic content, these characteristics do not directly correlate to soil strength. They pertain to other soil properties that, while important for overall soil health and function, do not measure the actual ability of soil to resist deformation.
