Soil Bearing Capacity. Soil bearing capacity refers to the ability of soil to support load applied to the ground. Bearing capacities have a safety factor built in to prevent failure. So, the ultimate bearing capacity would be its perceived point of failure with no safety factor built in. Pole embedment depth is calculated based upon frost heave
