Ultimate bearing capacity refers to the maximum load that soil can support without experiencing failure or excessive settlement. It is a critical factor in civil engineering and construction, as it helps determine the safe load limits for structures like buildings and bridges. Engineers assess this capacity through various methods, including soil tests and calculations. Understanding ultimate bearing capacity is essential for ensuring the stability and safety of structures. If the load exceeds this capacity, it can lead to soil failure, resulting in structural damage or collapse. Proper evaluation helps in designing foundations that can adequately support the intended loads while maintaining safety standards.
