| Learn more about the need to consider uplift pressure when designing a gravity structure at DamFailures.org |
When a dam impounds a body of water, it will experience a load or force commonly referred to as hydrostatic pressure. A variety of other forces such as uplift pressure, earth pressure, silt pressure, wave pressure, wind pressure, ice pressure, seismic acceleration, hydrodynamic pressure, and thermal stress from ambient temperature changes can also act on the dam depending upon site conditions. Global stability refers to the ability of the dam to withstand all design loading conditions with adequate safety margin. This is a function of the geometry and material properties of the dam as well as the magnitude and combination of loads acting on the structure.
