A concrete gravity dam has the following dimensions: downstream side h2 H ----று Dam B- W2 н hi WH b B Data: H = (85+ ax0,5) m B = 75 m b= 15 m h1 = h2 Crest width = 8 m Free board = 5 m Uplift pressure: at Heal: 100% at Toe: 0% Neglect the gallery drainage effect on uplift pressure.. Density of concrete: 2400 kg/m”. No tail water. Foundation condition: Inferior condition with limestone. Consider self-weight, hydrodynamic pressure and uplift pressure. Q1: Considering the above figure, calculate the forces acting on the dam. Q2: Check the stability of the dam for rotation and over turning Hint: a: The Last digit of the student's number. Write the question and answer with your handwriting (Except tables). Consider the following figure.
