4. Levels were taken at every 40 m along a piece of ground. The following observations were recorded: Distance(m) 0 40 80 120 160 200 105.0 114.2 123.6 128.0 130.20 125.60 Elevation (m) A cutting is to be made for a line of uniform gradient through the first and the last point. Determine its gradient. Calculate the volume of excavation if the formation width is 8.0 m, with side slopes in cutting being 1.5:1, and the natural ground slope is 10:1. The ground across the centerline is level.

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.
A site consists of a 12 m thick saturated clay deposit underlain by bedrock. The clay has ?=20.0?N/?3and ??=40?N/?2 . If an excavation is to be made at a slope angle ?=25° to a depth of 10.0 m, what would be the factor of safety FSs? What type of failure circle would you expect?
