A 24m high concrete gravity dam will be constructed with the dimensions shown in the figure below. The dam is composed of three blocks of equal heights. It is intended to implement an internal drainage facility, which would reduce uplift pressure by about 20%. Carry out a stability analysis for the upper block only considering usual and unusual loadings. (50p) Given: • There is no tailwater, • Compressive strength of concrete, Gc-35000 kN/m² • Shear strength of concrete, ts= 5000 kN/m² • Coefficient of friction between concrete blocks and concrete-foundation, f=0.75 • Specific weight of water, Yw= 10 kN/m³, Specific weight of concrete ye = 24 kN/m³, • Depth of sediment accumulation, h, = 3 m, Angle of repose 0=32°, Specific weight of sediment y = 11 kN/m³. 24 m te=0.0475 H₁ +2.392 H*=0.1075 H₂ IV:IH A 24m high concrete gravity dam will be constructed with the dimensions shown in the figure below.
