Draw a flow netlfor the case of a long concrete dam shown in the Figure below and calculate the quantity of seepage underneath the dam. The soil underneath the dam is homogeneous and isotropic with a coefficient of permeability of 1.8 x 106 m/s. Determine the minimum weight of the dam required to maintain a factor of safety of 1.5 against the uplift of the dam. If the saturated unit weight of the soil is 18 KN/mP, check whether quicksand...

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...

20 A concrete column with hollow circular cross section is under external loads as shown in Figure 1. Horizontal distributed load is defined by w=1/8*x’ function and its value reaches to 8 kN at the top of the column. Also, 50 kN vertical load is applied from the top of the column and its application point is 400 mm away from the centroid of the column as shown in the figure. Concrete column has hollow circular cross section and outer...
