Which of the following statements correctly describes the forces acting on a gravity dam?
- 1Gravity dams are designed to float on the reservoir, using buoyant forces to counteract the hydrostatic pressure of the water.
- 2The dam resists the water pressure solely through arch action, making its weight inconsequential.
- 3The stability of the dam is mainly due to its weight, which counteracts the hydrostatic pressure, uplift pressure, and other environmental forces.✓
- 4The dam primarily relies on its own weight to resist the horizontal thrust of water, with no significant role played by hydrostatic pressure.
Correct answer
The stability of the dam is mainly due to its weight, which counteracts the hydrostatic pressure, uplift pressure, and other environmental forces.
