A gravity concrete retaining wall is shown in Figure $2.$ The properties of the backfill and the foundation soil are also shown in the figure. Use an active earth pressure coefficient Ka $=0\mathrm{.}212.$ Determine the external stability of the retaining wall in terms of bearing capacity. Yes, this is the same problem as your last homework. Yes, you can $($and should$)$ just copy over relevant information to now check bearing capacity.
