1. A gravity dam is shown in Figure 1. Assume the coefficient of friction between the dam base and the foundation is 0.75, the specific gravity of concrete is 2.5, and uplift forces exist on the base of the dam. Neglect earthquake and silt (sedimentation) forces and take the unit weight of water as 9.81 kN/m². The freeboard is 3.0 m. Calculate the safety factor against the sliding and overturning. Check whether the dam is safe against sliding and overturning...
Q.5) Water backs up behind a concrete dam as shown in Figure below. Leakage under the foundation gives a linear pressure distribution under the base of the concrete dam as shown in Figure. If the water depth H, is too great, the dam will topple over about its toe (Point A). For the dimensions given, determine the maximum water depth. Base your analysis on a unit length of the dam. The specific weight of the concrete is 23.7 kN/m”. (Answer...
