- Problem 1: A man-made 30 ft tall, 1.5:1 slope is to be build as shown in the figure. The soil is homogeneous with shear strength parameters c = 400 psf and φ = 290 . The moist unit weight of the soil is 119 pcf above the groundwater table and the saturated unit weight is 123 pcf below. Using the ordinary method of slices, compute the Factor of Safety (FS) along the trial failure surface shown. (Hint: Please note the unit weight is changing within the same slice.) Note 1: Use the same number of slices and dimensions as provided. Document ALL the calculations of weight (W) for each slice. Note 2: Document your solutions by following the same approach illustrated in the class, including a summary table showing all the variables and calculations involved in assessing FS.arrow_forwardhow to manually plotting by coordinatesarrow_forwardmapping surveys/mappingarrow_forward
