CEG 4012 Homework 7 Due Mon. Nov 7 th 2011 Name:_________________________________ Show All Work 1. A small hydroelectric earthen dam in Martin County was constructed several years ago without filter drains and has begun to show seepage on its face. The thickness of the base roughly equals the dam height (i.e., D=2). The face has a 1:1 slope and it is 40 ft high. The dam was constructed with soil from a nearby borrow pit and the soil properties of both the dam and the base are very similar: γ m = 115 pcf, γ sat = 125 pcf, φ u = 15°, c = 1000 psf, φ ' = 35°, c' = 625 psf If you conservatively assume that r u = 0.5 (saturation), what FS do you calculate ( long term stability ) using the Cousin’s Charts? What is the location of the center of the critical failure surface? 2. Using the Cousin’s charts, determine the FS for an embankment slope with the following conditions: H = 55 ft, 1:1 slope, γ = 110 pcf, c = 600 psf, φ = 20° when r u = 0, 0.3. What is the critical FS for each case of pore pressure? What type of failure would be expected based on this

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
