4.2.6 Gravity (concrete) dam analysis, stability (overturning, sliding), stress and material failure
Determine the maximum and minimum vertical stresses to which the foundation of the dam will be subjected from the following data: Total overturning moment about toe (ΣMo)=1.2×10⁶ kN-m; Total resisting moment about toe (ΣMR)=2.5×10⁶ kN-m; Total vertical force above the base (ΣV)=6×10⁴ kN; Base width of dam = 55m; Slope of d/s face = 0.8:1. Also calculate the maximum principal stress at the toe. Neglect tail water depth. [2+2+2]
