Unformatted text preview: based on this particular failure surface. (Aren’t you glad that the problem was not to iterate and find the critical failure surface?) 2. Assuming that the previously described failure surface is the critical surface and referring to your answer to Problem 1, Part D of the Previous Homework Assignment, comment on how excessive the Coulomb-based earth pressure coefficient is in this particular case. Also, determine the interface friction angle that would be needed in Coulomb’s method to produce a result consistent with Terzaghi’s log-spiral-based method; express your answer in terms of the ratio δ / φ....
