Answer Happy

lateral earth pressure
please remeber that
A 9.6 m deep excavation is to be undertaken for an underground car park. The soil profile is shown in the figure below. Please take the yo = 9.81 kN/m and the GWT at a depth of 1.60 m. 9 = 75 kPa 1.60 m C-OkPa = 34 y = 16.40 kN/m GWT V 0.90 m C=85 kPa 0=0 Y=17.40 kN/m 9.60 m 3.25 m C 16 kPa 0-23 Y = 18.60 kN/m 2.15 m C=0 kPa +42" y=19.20 kN/m 1.70 m C-18 kPa 022" y = 18.70 kN/m 1. (30 marks) Please plot the active earth pressure diagram for the soil. 2. (30 marks) For the soil pressure, compute the resultant active thrust and its location, 3. (15 marks) Please plot the active earth pressure diagram for the water. 4. (15 marks) For the water pressure, compute the resultant active thrust and its location. 5. (10 marks) Compute the combined soil and water resultant active thrust and its location.
