6-12 Use Coulomb's method to determine the magnitude and direction of the total lateral force against the retaining wall of problem 6-5. Assume the friction angle between the wall and the soil to be 2/3*phi. Make one trial only, using an assumed failure surface at an angle of 60 degrees from horizontal. Problem 6-5 is: Use Rankine's method to determine the magnitude and location of the resultant active force against a retaining wall 6 m high. There is a water...
