PROBLEM. I If there are no earthquake, wind, ice, wave and tail-water check the stability of the concrete gravity dam at its foundation section (base) AB as indicated in the figure. The friction factor between the foundation base of the concrete dam and the rock foundation is f= 0.75. The allowable compressive and shear stress's of the rock foundation are 3500 KN/m² and 2500 KN/m², respectively. Both the allowable compressive and shear stress's of the concrete is 3500 KN/m². The specific gravity of concrete is 2.4. Also the specific gravity of water is y=9810 N/m³. The length of the dam normal to the picture (figure) is 1 m.
