For the slope given below, consider the slip surface divided into thirteen slices. Based on the ordinary method of slices, calculate the Resisting Force in kN for slice #3 for long term conditions. (Acceptable tolerance = 4%). The geometry of slice #3 and the soil properties are provided in the tables below. The height of water at the middle of the slice is hw = 3.0 m hint:Given that the soil is partially saturated in Slice#3, the total weight of the slice (W) should be calculated by summing up the weight of the area that is below the water table (saturated soil) and the weight of the area located above the water table (moist soil).
