Question $2[25$ Points$]$

A cantilever retaining wall is retaining compacted fat clay as shown below. The shear strength parameters of this fat clay are provided in the figure below. Full active earth pressure conditions are expected.

Answer the following questions.

What issues we would face if we apply Rankine's Earth Pressure theory to estimate the active earth pressure for this backfill? $[4$ points$]$

What is the best earth pressure theory to use here? $[4$ points$]$

Using the method identified in part $2,$ plot the distribution of the active earth pressure. $[8$ points$]$

What is the location of the point of application of the earth pressure force acting on the retaining wall? $[9$ points$].$
