A New Sand Embankment Is To Be Constructed On Top Of An Existing Sand Foundation Soil As Shown In The Sketch Below Assu 1 (130.04 KiB) Viewed 21 times

A new sand embankment is to be constructed on top of an existing sand foundation soil as shown in the sketch below. Assume that the properties of the sand foundation soil are the same as the properties of the new sand embankment material. The ground water table is located deep below the ground surface. 2 Sand c' = 0, °' = 32° y = 120 pcf 20 ft a) What failure mechanism will you select for this slope? and, why? Draw and label your estimate of the critical (i.e., lowest factor of safety) failure surface on the figure above. b) What is the factor of safety that Slide would calculate for the given parameters and geometry based on a comprehensive search for the critical failure surface? c) Do you recommend total stress or effective stress analysis for this slope? Further explain about your choice of analysis.
