Web8 Jul 2024 · In these equations, which have been modified by some authors [1, 18, 19], the soil strength parameter is represented by N SPT. According to Bowles , an accumulation of field observations showed that Meyerhof’s equations are too conservative. Thus, this author proposed an increase in the allowable bearing capacity of approximately 50% for a 25 ... WebThe standard penetration test ( SPT) is an in-situ dynamic penetration test designed to provide information on the geotechnical engineering properties of soil. This test is the most frequently used subsurface exploration drilling test performed worldwide.

Average SPT values for the top metre of sand are in the range N = 22 − 41; a conservative average value of N = 25 will be assumed for determining the allow-able bearing pressure. A square base of 2 m × 2 m is initially assumed. From Fig. N.1, the allowable bearing pressure is n a = 280 kN. This gives a capacity of P a = n a BL
