WebSafe bearing capacity of soil equals to the ultimate bearing capacity divided by a safety factor (usually 2-4). ultimate bearing capacity is defined as the maximum unit pressure a soil can sustain without permitting large … WebMay 12, 2024 · In the event that subgrade modulus is not available in the soil report, it is safe to assume the subgrade modulus by the following formula based on Foundation Analysis and Design by Joseph E. Bowles pp503: k s = 40SFqa. Where: 40 is constant also equal to 12 when using English units; SF: safety factor is usually taken as 2.5
