WebTable 2 is based on data for relatively clean sands, thus, sands with a significant amount of clay/silt-sized material will fall in the lower portion of the range. The reported values of effective friction angle (ϕ′), based on SPT N60 values, should be reduced by 5° for clayey sands and should be increased by 5° for gravelly sands. Web11 Dec 2024 · Su et al. conducted a numerical analysis on the effect of soil plugging and compared it with field measurements, and they found that the ultimate bearing capacity of the soil plug had a linear relationship with the soil parameters Standard Penetration Test(SPT) and CPT.
