2. Gravity Dams

Try these first

1. 1.

   What is the primary force that gravity dams utilize for stability?

   Hint

   Think about what makes the dam heavy.

2. 2.

   What can occur if the uplift pressure exceeds the self-weight of a gravity dam?

   Hint

   Consider what happens when something gets too light.

3. 3.

   What is the primary force that gravity dams rely on for stability?

   • A) Flexural strength
   • B) Weight of the dam
   • C) Uplift pressure

   Hint

   Think about what keeps the dam firmly in place.

4. 4.

   True or False: Gravity dams primarily resist horizontal forces through their weight.

   • True
   • False

   Hint

   Consider how weight counterbalances forces.

5. 5.

   If a gravity dam weighs 5000 tons and is subjected to a hydrostatic pressure of 2000 kg/m² on 4000 m² of its face, calculate if it can sustain the hydrostatic force considering its weight.

   Hint

   Calculate the forces and compare them to the weight of the dam.

6. 6.

   A gravity dam has a safety factor of 1.5 in terms of sliding. If the total horizontal force at the base is 1500 kN, what minimum resisting lateral force must the dam provide to ensure stability?

   Hint

   Consider the safety factor when determining the minimum resisting force.
