Question 2: A new fill pad is to be constructed at your site. Figure below shows the approximate existing soil layer profile along the cross-section. It also shows the proposed location of the fill layer and the slope edge. The imported fill material consists of clayey-sand and has been found to have an undrained strength of 35 kPa and the total unit weight of the fill is 19.0 kN/m3 after placement. The fill edge slope will be 2H:1V. Other soil layers are as follows: a) FM1-FM4 is a normally-consolidated clay with an average undraind strength of 15 kPa, and total unit weight of 18 kN/m3. Groundwater is at elevation 0, which results in standing water in front of to the slope. b) Evaluate the stability of the fill embankment based on the information above. c) Does the slope have an acceptable factor of safety? 40 30 20 10 Fill 0 Elevation Relative to Mean Sea Level (m) FM1 -10 FM2 -20 FM3 FM4 -30 -40 ז 0 10 20 30 40 50 60 70 80 90 100 110 120 B-B' (m) Cross section showing site profile and proposed final fill edge slope.
