Subject : Geotechnical Engineering Give me right solution according to the question. A 6m vertical cut has been excavated from a dry cohesive loess soil deposit. For the plane shown passing through the vertical cut face, estimate whether or not a shear failure is likely.
In the following Figure, the survey of a proposed cutting shows that the depths at 20m intervals are 0.0, 0.9, 1.5, 3.2 and 3.3 m. Given that the roadway is to be 5 m wide and that the cutting has 45° side slopes, calculate: (a) The plan surface area of the excavation ABCD, Dr (b) The actual area of the side slops, ABE and ENGIN CDF.
