2. A cut slope was excavated in sand. The slope is shown in following figure. 18m o. 5 m 14m 30 To find the properties of the sand, representative samples were taken for the soil and tested in a triaxial apparatus. A consolidated drained triaxial test was conducted. The result is given below: Chamber pressure = 103 kN/m? Deviator stress at failure = 234.6 kN/m? We know the unit weight of the sand is 16 kN/m. Use the ordinary method of slices (use 7 slices) and estimate the factor of safety against sliding for shown slip surface and comment on the calculated factor of safety. Please note that: 1. The figure is not in scale. You may resketch it in scale and calculate the factor of safety
