at the Question III (25%): An embankment was constructed utilizing a geosynthetic layer a base as well as at two intermediate layers within the embankment to provide greater stability for enabling sufficient resistance against bearing capacity failure. On the other hand, after the construction had finished and when the embankment started to the operation, a sliding has initiated and mobilized through a failure surface as shown in Figure below due to deficient (unsatisfactory) compaction of soil fill (i.e. lacking of proper compaction effort according to technical specifications) in the embankment during construction. Therefore, the embankment undergoes a failure that will result in the collapse of this infrastructural facility. In light of this, calculate: (a) [10%] The magnitude of Total Driving Moment (b) [10%] The magnitude of Total Resisting Moment (c) [5%] Factor of Safety (FS) against Overall Slope Stability Failure y T3=T + 1 T2=T T₁ =T R 1.3y 1.6y Xe We le Te Given that: We = 2000 kN/m Te = 30 kN/m² le = 15 m Xe = 15 m T = 20 kN/m y = 10 m R = 25 m Wr= 750 kN/m Tf=40 kN/m² Ir = 20 m xf=5m R Geosynthetic Layers Xf W₁ Ir Tf
