A Slope With Angle 22 And Depth 6 M Is Excavated Into A Saturated Soil Deposit With Critical State Friction Angle Of 2 (19.25 KiB) Viewed 21 times
= A slope with angle 22° and depth 6 m is excavated into a saturated soil deposit with critical state friction angle of O' = 36° and unit weight y = 20 kN/m3 (unit weight of the soil is the same above and below the top flow line in Figure 2). The slope has a drainage system with a drain located at the toe of the slope, water moves from the surrounding soil to the drain. Assuming a slip circle with center at O and using the method of slices, calculate the factor of safety for this slope, in drained condition with steady-state seepage to the drain. The necessary information for each slice in Figure 2 is provided in Table 1 below.
