The braced-cut excavation will be constructed with the sheet pile in the layered clayey soil (Fig). The following information is given: • The width of the cut B = 6 m • The length of the cut L = 20 m • The height of the cut H = 8 m • For the 1st layer: H = 2m, y = 19.5 kN/m3. Cu = 40 kN/m2 • For the 2nd layer: H = 3m, y = 18.5 kN/m2. Cu = 25 kN/m2 • For the 3rd layer: H = 3m, y = 17.5 kN/m². Cu = 30 kN/m2 • The center-to-center spacing of struts in the plan s = 5 m • The allowable flexural stress of the sheet file Oall = 180 MN/m2 (a) Determine the strut loads at levels A, B, and C. [14 marks] (b) Determine the sheet-pile section modulus. (12 marks] ) Determine the factor of safety against bottom heave. [4 marks]
