7. A sandstone dip slope has an angle of 42° and a potential failure plane exists at a depth of 40 m in the slope-normal direction below the surface. The sandstone has a density of 2,600 kg/m³, a cohesion of 1.7 MPa, and an angle of internal friction of 26°. Under dry conditions, what is the hillslope's factor of safety to the nearest whole number?
A granular soil has Yeat = 18 kN/m³ and o' = 32°. An infinite slope is required to be made from %3D this material. If seepage occurs parallel to the surface of the slope and factor of safety of 1.5 is needed against slope failure then the value of safe angle of slope is degree.
An unsupported slope of height 15 m is shown in the figure (not to scale), in which the slope face makes an angle 50° with the horizontal. The slope material comprises purely cohesive soil having undrained cohesion 75 kPa. A trial slip circle KLM with a radius 25 m, passes through the crest and toe of the slope and it subtends an angle 60° at its centre O. The weight of the active soil mass (W, bounded by KLMN) is 2500 kN/m, which is acting at a horizontal distance of 10 m from toe of the slope.

Stop D: The High Level LRT bridge section (UTM 333280 5934116, NAD 83) Immediately west of the LRT bridge is an small cliff in which are displayed 6-7 m of fine-grained sediment that shows almost horizontal layers, believed to have formed in the last 8000 years. The exposure is parallel to the river, and is preserved from erosion and is accessible because and engineered berm has been constructed between the section and the river. At the top of the section one can see the remnants of a brickyard that operated at the site between 1898 and 1913. A huge flood destroyed the yard in 1915, giving a good impression of the magnitude of peak historic flooding and flows. Within the lower third of the cliff there is a conspicuous whitish layer, and several brown to red layers. Grains in the whitish layer have been dated using isotopes to between 7584- 7682 years before present. This age coincides with the eruption of Mount Mazama, a huge volcano that existed on the site of Crater Lake, Oregon.…
