Tag: SPT Ultimate Bearing Capacity of Footings Based on SPT Values (N)

Standard Energy Ratio Res Applicable to N Value The effects of field procedures and equipment on the field values of N were discussed in Chapter 9. The empirical correlations established in the USA between N and soil properties indicate the value of N conforms to certain standard energy ratios. Some suggest 70% (Bowles, 1996) and others 60% (Terzaghi et al.,
