Undrained bearing resistance

From previous calculation, total overburden under base is ct^ b = 31.5 kPa

Partial resistance factor for SLS: yrv sls = 3.0 ©

Ultimate resistance is qult = (n + 2) x cud x dc x sc + avk b = 348.1 kPa qult

Design resistance is qRd --- 116 kPa

Drained bearing resistance

Effective overburden under base is ct' vk b = CTvk b - ud = 26.6 kPa From overburden q'ult = Nqx CT'vkb = 283.6kPa

From self-weight q'ult = NYx (Yk-Yw)x—= 126.1 kPa Total resistance q'ult = q'ult = 513.3kPa q'ult

Design is unacceptable if the degree of utilization is > 100% Verification of drained bearing resistance

Design is unacceptable if the degree of utilization is > 100%

Explicit verification of serviceability Actions and effects

Increase in bearing pressure is Aqd = qEd - CTvk b = 150 kPa

Immediate settlement (Christian & Carrier)

Settlement factor for D/B is — = 0.6 , giving ijq = 0.93 (from chart)W
