Question
A compacted earth fill is constructed on a soft, saturated clay (figure below). The fill was compacted
to an average dry unit weight of 19 kN m3 ⁄ and water content of 15%. The shearing strength of the
fill was determined by CU tests on samples compacted to representative field conditions. The shear
strength parameters are ?? = 45 kPa, ??′ = 34°, and ???′ = 28°. The variation of undrained shear
strength of the soft clay with depth as determined by simple shear tests is shown in the figure below,
and the friction angle at the critical state is ???′ = 30°. The average water content of the soft clay is
40%. Compute the factor of safety using Bishop’s simplified method. Assume that a tension crack
will develop in the fill.
