B C 20 ft Y=110 Ib/ft O= 20° c = 400 Ib/ft 50 25° This question has three parts. For the given slope conditions (ABC) and failure surface (AC) shown in the figure: 1) Calculate the factor of safety against sliding. 2) Calculate the factor of safety if c = 0. 3) Calculate the factor of safety if the groundwater level rises to point A.

Please round to the nearest One (i.e., 1). PLEASE DO NOT USE COMMA (S) ON YOUR ANSWER!!! Moist unit weight of soil, gamma = 112 pcf %3D Saturated unit weight of soil, gammasat = 124 pcf Cohesion of soil, c 0 psf The factor of safety, FS = 2 The internal friction angle of soil is 30 degrees B = 5 ft, D, = 5 ft, h = 3 ft A strip footing is shown below. Determine the followings: Unit weight of soil = y c' Qal Groundwater table Ysat B 1. Ultimate bearing capacity, qu = psf 2. Allowable bearing capacity, qa = psf

Ta Hypothetical Case: Slope Soils Natural or man-made slope Potential failure plane 01 35° |0₁-652 0₁ = 52 kPa a = 35° 03= 12 kPa Horizontal Slope failure (landslide) will be triggered at any point along the potential failure plane when the shear stress exceeds the shear strength of the soil mobilized in the opposite direction.

A level site underlain by fully saturated clays is cut over a few days as shown in the figure below. The water table is located at the ground surface across the site. Determine the resisting
