tan vv

For cohesion: Nc = (Nq - 1) x cot(d) = 20-7 For self-weight: NY = 2(Nq - 1) x tan(d) = 9

Depth and shape factors

Are the same as for Design Approach 1

Undrained bearing resistance

Total overburden at foundation base is avk b = Yk x d = 31-5 kPa Partial factors from set R2: yrv = 1-4 ©

Design resistance is qRd qult YRv

248.6 kPa

Drained bearing resistance

Effective overburden at foundation base is ct' vk b = CTvk b - Ukb = 16.8 kPa From overburden q'ujt = (Nqx a'vk b) = 179 kPa

From self-weight q'ujt =

x (k - Yw)x J Total resistance q'ujt = q'ujt = 408.7kPa

Design resistance is q'Rd =-= 291.9kPa
