a) As a geotechnical engineer, explain why construction of foundations and other loads (structures) leads to a compression of soil layers. b) During the construction of a retaining wall, it was noticed that the wall does not yield toward the backfill or away from the backfill. Explain this phenomenon. Sketch a diagram to explain your answer. c) Let us consider the retaining wall shown in Figure below. The height of the wall is 9.75 m, and the unit weight of the sand backfill is 18.7 kN/m³. Using Coulomb's equation, calculate the active force, Pa, on the wall for angle of wall friction 8'=14°. Also, comment on the direction and location of the resultant.

4) You are working for a construction company and are building a school. In digging the foundation, you find water at 7 m below the ground surface (bgs). One hundred meters away, you find water at 7.5 m bgs. Choose the datum as the confining layer that is at 25 m bgs. What is the piezometric surface at each point, the direction of groundwater flow, and the hydraulic gradient? Note: Assume the confining layer is parallel to the surface (this may or may not be true but assuming this allows us to simplify a complicated problem). Include a diagram in your solution. vni of al nomingizan listnicy Instancos ritiw 21uorl owl 2126l 16dt mot2 & Tab
