question in figure
It was found that the backfill against a retaining wall (6 meters in height as shown in
Figure 3) has specify weight y= 16 kN/m³ when its water content w= 5 %, S = 0.12, its
internal friction angle was measured as 30° (take G,= 2.7 and xw = 10 kN/m³).
a. Predict distribution of lateral stress on this retaining wall along its depth in its “at
rest" state, and its resultant force.
b. Rain leads the backfill water content increase to 10% in its upper half, and
saturated in its lower half, find and plot its lateral stress and pore pressures along
its depth in an active state.
a) Referring to Figure Q2 (a), the vertical stress increase at point A is 25 kN/m² due to
application of line loads q1 and q2. Determine the magnitude of q2.
