- Explain about the Noncircular slippage plane for slope stability analysis, Janbu method.1. The Maine DOT is constructing a section of the E-W highway along a 25 ft. high natural rock embankment. The slope of the rock face is 1.5H:1V. The DOT has requested a preliminary investigation of the factor of safety against slope instability. Rock cores gathered during the subsurface investigation indicate the predominant orientation of discontinuities varies between 9 and 19 deg. They are targeting a factor of safety of at least 1.5. Assuming a planar failure surface that extends through the toe and a friction angle of 25 degrees along the discontinuities: a. Plot the FS on the vertical axis for failure inclinations ranging between 9 and 19 degrees (horizontal axis). Is the required factor of safety satisfied? (Hint: create a spreadsheet and show one example calculation). H = 25 ft 1.5 Traffic Surcharge Pressure Failure surface Inclination, B Rock o'= 25 deg Y = 145 pcfWhy does slope stabilty of the soil is dangerous in building construction?
- An understanding of rainwater drainage and the groundwater levels is of high importance in establishing slope stability, especially when that slope borders a dam reservoir. Because: A. The presence of water can cause smooth fractures to slip easier B. Water comes in between the grains and reduces the coherence of the rock C. A landslide facilitated by water presence may cause a tsunami over the dam wall D. All of the above E. None of the aboveSubject : 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 cut slope is to be made in a clayey soil to permit construction of a new highway as shown below. A slope stability analysis is to be performed along the potential shear surface shown in the figure. The soils are silty clays with c' = 18 kPa, phi’ = 20degree.
