Solving using Eurocode 7, design approach 1, combination 2

A rectangular foundation of plan size 5 (B) × 10 (L) m is to be designed to carry a
load of 86.6 MN (0.6 Gk + 0.4 Qk) in fully drained conditions in the following soil:
Ck' = 5kPa; Ok' = 38°; Ydry 20 kN/m³;
Ysat =
22 kN/m³; Y conc= 25 kN/m³
a. Determine a suitable founding depth (equal to the foundation thickness),
assuming the groundwater table is well below the foundation level.
b. What if the groundwater level is getting rise? Determine design bearing
resistances using the determined foundation depth from the above question.
(i) up to the underside of the footing (foundation level)
(ii)
up to the ground surface.
