I need complete answer so plz make it perfect and easy to understand for me A cantilever sheet pile wall is required to support a temporary excavation, as shown inthe accompanying Figure. Using the available information, determine the depth ofpenetration of the wall into the stiff clay layer, and the anchor force per unit length ofthe wall (i.e. normal to the plane of the Figure). Assume the soil above the groundsurface to be fully saturated. In carrying out your calculations, consider two differentapproaches: (A) Apply a factor of safety FS on the overall passive resistance, which isusually taken at around 1.5 while using the nominal values for the strength parametersshown in the Figure. (B) Apply a mobilization factor Fo to the friction angle so thatthe design value is obtained from the nominal value as o 'design = p'er / Fo where themobilization factor is about 1.5. Likewise, in the second method the design undrainedshear strength is obtained from the corresponding nominal value as (Su), design= Su / Fuwhere the mobilization factor Fu is about 1.75. Compare the results between the twoapproaches. Also, discuss the most critical loading condition i.e., undrained (short-term) conditions using total stresses and c = Su , 9 = 0, or drained (long term)conditions using effective stresses and o = per', c=0. Justify your answers.1 mAnchor0,5 mSoft clay:6 mY= 18.8 kN/m³, o', = 30°, s, = 25 kPa,8 = 0°Stiff clayY =19.2 kN/m³, o', = 28°, s, = 100 kPa, 8= 0°Figure: design considered.
