Actions and effects

Partial factor from Set A1: yg = 1.35

Material properties and resistance

Partial factors from Set M1: = 1 , yc = 1 , ycu = 1 , yRe cuk

Design undrained strength cud =-= 75 kPa ycu

Design angle of shearing resistance -d = tan - = 20°

Design effective cohesion c'd =-= 5kPa yc

Verification of strength for short-term (undrained) conditions cud

Design stability number (undrained) Nud = -:-

From Taylor's chart, the maximum design slope angle is Pd = 74.5°

Degree of utilization is a,
