The cohesion ( Cu ) found to be from the mohr circle graph = Cu 432 kPa The angle of friction ( ) фu also found to be = . фu 8 5⁰ 5- Brief Discussion The internal angle of friction for saturated clay soil should be zero at undrained condition ( ф = ) u 0 and ( = ) τ Cu The failure angle ( θ ) for fully saturated at undrained condition should be ( = θ 45 ) as ( ф = ) u 0 which is calculated from the following formula ( = θ 45 + ) 0 фu2 However, the measured ( θ ) was found to be ( = θ 50 ) Because of the errors involved in this experiment, the results turned up to be slightly different from the ideal case The errors are 1. Calibration reading 2. Rounding off the experiment results
