An unreinforced highway embankment is to constructed out of compacted clay on a soft soil as shown in the figure below. In order to ensure the stability of the embankment during construction, staged construction will be necessary. Provide your design with a construction schedule from start of construction through placement of the first lift and then to a point of 80% consolidation for the first lift. Also evaluate the shear strength after placing the first lift and assess whether the full embankment load can be added for the next lift. Use PVDs to shorten the construction period and accelerate construction. Ignore the effects of smear during installation of the PVDs. Assume the required factor of safety for the slope is 1.3. y = 20 kN/m, c = 2000 psf, 0 = 0 deg 2H: 1V 7 m 2H:1V 7 m Impermeable bedrock Normally consolidated soft soil, y = 16 kN/m3, cu = 200 psf. 0 = 0 deg, cv = 3 x 10-8 m/s, kr/kx = s[/cv = 3, Cc = 0.5, 0 = 0.6 An unreinforced highway embankment is to constructed out of compacted clay on a soft soil as shown in the figure below.
