Question:

The following are the average values of cone penetration resistance in a granular soil deposit.

Depth (m) …………………… Cone penetration resistance, qc (MN/m2)

2 ………………………………………… 1.73

4 ………………………………………… 3.6

6 ………………………………………… 4.9

8 ………………………………………… 6.8

10 ……………………………………..… 8.7

15 ……………………………………….. 13


For the soil deposit, assume γ to be 16.5 kN/m3 and estimate the seismic ultimate bearing capacity, quE, for a continuous foundation with B = 1.5 m, Df = 1.0 m, kh = 0.2, and kv = 0. Use Eqs. (7.47) and (7.48).


Eqs. (7.47)

1 Static conditions: qu = qNg +yBN, b.

Eqs. (7.48)
