(c) A stable underground wall, at rest, is subjected to lateral pressure and water pressure as shown in FIGURE Q4(c). The total depth of the underground wall is 10 m and the water table is at 5 m below the ground surface. The soil's yt is 19.5 kN/m³, and o' is 38° for this normally compacted sandy soil. (i) Compute and sketch the effective at-rest lateral earth pressure and water pressure distributions against the wall. (ii) Determine the resultant force against the wall and its point of application.
