4.2.6 Gravity (concrete) dam analysis, stability (overturning, sliding), stress and material failure
The figure below (all dimensions are in m) shows the section of a concrete gravity dam. Neglecting the effects of earthquakes, check the stability of the dam. Also, calculate the intensity of the shear stresses on a horizontal plane near toe and heel. Assume the unit weight of concrete is 24 kN/m³. The allowable stress and average shear strength in the concrete may be taken as 2500 kN/m² and 2200 kN/m², respectively. Take μ=0.75. [12]
